Removed the change log because it was out of control.

very nice guide, just wondering about storms overload does the slow effect siege units? It isnt mentioned. Other than that theres I don't think you have left anything out.

I give u a sticker for the effert

[viiva]

That must've been a bitch to check. Kudo's for you.

[Audacious]

Insane. Got a lot of time on your hands?

[Black Isle]

It took approximately 100 minute game with 100 heroes. To confirm and check all skills ): And ofc older tests which are not intented for guide.

@LEMONS
I didn't noticed that overload slows them, I'll go check it than add if affects. Thanks.

Unfortunately overload don't affect them.

Formating error on March of the Machines.

Wave of Terror decreases attack too. Can you check if it works on siege units? It should since it is the same buff.

You are missing Scorch Earth's 4 dps that works on Siege units too. It is also based on Flame Strike that can target mechanical units.

Edit:
Entangle uses Ensnare to stop the target not a Pause effect. There is quite a big difference especially since Pause will prevent you from attacking and disables evasion.

Good reference! Every hero guide writer should consult this when writing their guide.

[SNOW37]

i think greater bash should stay seperate as it different from every other bash. But ya a very good guide

[Black Isle]

They are seperate actually, i think you didn't noticed. I can increase the distance between them if you want (:

[SNOW37]

When crixalix hits a organic unit it will receive a 0.25 buff. When unit dies within that interval it will explode and deal damage around them. Siege units are also affected from this damage.

[SNOW37]

yes bt you have the skill as an active skill...
maybe change it to passive?

silly rabbit

[Black Isle]

But i use it really actively! Sorry, I'll fix that Thanks..

True, but only if you manually target the siege unit.
