Alchemy? Worth it?

[Shd]

Even with lvl 3 alchemy from beginning there is no possibility to upgrade all spells . Answer to this question (to get or not to get alchemy) depends on your playing style.

When i did play on easy difficulty then my thoughts was "i don’t need alchemy". When i played on impossible difficulty, then at lvl 18 i understood that alchemy is "must have" (and sooner the better), because there you cannot use just 3-4 offensive spells to win with minimum or even zero casualties. You need to neutralize enemy ranged units (hypnotize, shackles, fear etc.), slow strong melee packs (slow, trap), make attack enemy your strongest unit (target) etc, etc, etc. In that case you need to change tactics almost on every enemy pack to win them, so you need variety of spells
