Dimension war guide

updated: 2015-02-09
Dimension war is a very nice new feature of Wartune. It's a refined version of the underground palace. If we shall ever see underground palace again is a mystery, but I would regret not being able to collect the mount from there.

How to start

To start this event, you must speak to NPC Lycus in Cloud city (between sylph arena and market). He will give you a basic coordinate chest. Opening it, you will get a "basic XX dmiension coordinate", which you need to use. After that, you can enter your dimension through the mystic gate in your city.

Movement

These Wartune dimension can have 6 elemental forms, like your sylphs. Each day, you start with 1500 energy in the dimension. Each movement to a new square costs some energy. The higher your given resistance, the less. For this reason, you are recommended to have all 6 types of sylphs, and equip the proper type while moving inside. A weak, white sylph will suffice, monsters are very weak (except the bosses in advanced / expert). It is also good to convert your resistance crystals to the type of the dimension. When I entered a dimension with the wrong sylph, one move cost 50 energy. When I equipped the proper sylph, one move cost only 30 energy. After I converted 5 lvl 5 resist crystals to the dimension's, movement cost was reduced to 21 energy (further decreased to 20 after I entered the 2^nd level). You can reduce your movement cost to as low as 10 energy, if you have multiple dimensions of the same type conquered!

Please note if you move to a square which you already visited, it cost you no energy.

The map

This mini game is pretty simple, you will discover how it works very fast. It has 5 levels, each level consist of 12 x 8 squares for basic and intermediate (the advanced and expert levels are rougly 4 times bigger). When you move to a new square, you also see the neighboring squares around you, so you don't have to step on each to discover a level.
Also, there is a trick when moving around: after you discovered some of a level, you can move around clicking on any far square, and your toon will run there automatically.
My suggestion is that you run through each level in a S shape, so you discover every square using the minimum amount of energy. After you conquered the dimension, and get all the bonuses, you can come back to loot everything.

The goal

There are 2 things you must find on each map: the entrance to the next level, and the special objects (for example, Tree of Life in wind) which you must occupy to own the level. Some dimension levels need more than one object to occupy. To enter the next level, you must occupy all objects.

Loot

Unlike in underground palace, the loot here does not improve much further levels, unfortunately. You can find the same items like in underground palace (mahra, sepulcrum, skeleton key, beredin's wine etc). They also added the new items needed for making, refining and enchanting sylph equipment. There is also plenty of bound balens, but I did not see a spirit covenant or VIP like in underground palace, and no big treasure chest either. Instead of that, you get X chests in mail each day, where X equals the special objects you occupied. The 2 chests I got after 1 day contained one runstone, and one skeleton key, quite neglectable. After occupying last level, I got a chest, with the items inside you see on the first screenshot above.*

You can find merchants who sell items for balen, the prices are ridiculous as usual, the only good deal people report is mire rune (probably nerfed with today's patch).

Also there are kill/revive objects like in U.P., and some which increase your energy.
* Please note that the rewards have been severely reduced in February. See changes here.

Dimension types
There are 4 different dimensions: basic, intermediate, advanced and expert. Basic last for 10, intermediate for 14, advanced for 35, expert for 70 days. The loot you find inside is exactly the same, but intermediate has 10 levels. Advanced has 10 levels too, but each level is 4 times bigger. I haven't visited expert, but someone said it's 30 (!!) levels. With 10 energy per move, you can complete a basic in 1 day, an intermediate in 2 days, an advanced in a week, an expert, maybe a month? Do not try advanced or expert unless you have very high resist and can move for 10 energy!
You can get dimensions the following ways:

• collect dimension shards inside the dimension by killing guardians, and forging under blacksmith into a chest. 
• get lucky and open one from the dimension chest you get as a reward each day for completed dimensions.
• buy them for balen inside the dimension at a merchant.
• buy them in a balen sale.

Please note that these loots have changed in February, see more details here.

Tactics

Move in an S line, to explore the full level by spending a minimum amount of energy. With each level completed, the bonus you get increase, and movement cost is reduced. You should loot up everything outside of your path only after you conquered the dimension, and have no room for more dimensions in your Mysic gate.

You can buy an additional 100 energy for 45 balens (5 times a day). I don't think it's a good idea to spend balen on this, cost more balens than the reward worth, but sometimes when you need a few more steps to complete a dimension you can spend the bound balens you earned here.

Strategy

Dimensions give a good resist bonus, which is useful in combat. For this reason, I recommend doing dimensions which give protection vs the most popular sylphs: electro or dark. You have to try do to dimensions of the same type, so their bonus stack together, and you can move cheaper and cheaper. Ideally, if you collected a bunch of electro or dark dimensions, start doing whichever is more numerous. If you you have a small collection, then start doing something of which have the most (my first dimensions were fire).
You should start off doing a basic dimension. Convert your 5 best resist crystals to that type so you move for the minimal energy. After that, do one more basic, the one more: until your movement cost is reduced to 10. At this moment, you can do an intermediate. Keep doing basic and intermediate until your dimension list is full. Please note that with VIP9, you can have 5 dimensions.
When your dimension list is full, you can start looting them. In basic, open only the chests, in intermediate you can do the fights as well so you get more intermediate dimension shards.
The dimension has a lifetime, after that, it expires, and you need to summon a new dimension. You will always have enough pieces from killing the guardians to create a basic dimension chest. You can extend the dimension by using dimension essences, which are rare drop from the final chest. 
About advanced dimensions: eventually you will be "lucky" to find one in an intermediate reward chest. Do it ONLY if your movement cost is 10, and your other dimensions still have 5+ days lifetime. Advanced dimension levels are 4 times bigger than basic, but it has the same number of loot. So in other words, you get 4 times less loot for your energy. Still, the final resist boost is nice, so it's okay to do it (but only if the above conditions are met). Since the nerf, I don't think doing expert dimension is a good idea. You miss out an incredible amount of loot.

So this was a very nice event, good for non-cashers as well. Too bad they nerfed it, reduced the final resist bonus significantly, and severely reduced the treasure in the final chests.
