Now talk.

thats a long vid. cba to watch it really. cant you describe it and my opinion about combining spells in general: yes i love the way you can combine similar spells for better effect. and id love them to make a system so we can combine different spells aswell, but t seems hard. 85 spell effects, and if all could be combined thta would be.. ALOT of new effects..

That game looks fun. I like the spell combos.

Some spells might not work together like Fire and Ice (is that demonstrated somehow in the video)?

After watching that video I bought the game on steam just now. It looks like fun.

Every element and spell type can be combined in this game. Just watch it.
