ToME: the Tales of Maj'Eyal

I really like the change in Arcane Combat that lets you choose which spell will trigger, but I was thinking it would be cool if you could choose spells beyond the lowest level spells. The higher level spells are certainly more powerful, but it would be balanced somewhat by the much higher mana cost for the higher level spells. Triggering those spells would drain your mana much more quickly, but would give many more build options. Maybe even open it up to spells beyond the normal Arcane Blade list to allow for some crazy adventurer builds.

There's an add on for that. AstralInferno's Adventurous Arcane Combat. Played an adventurer using Arcane Combat and Reaver talents. Bone Spear is great with this because if the NPC dies when it procs the Vim cost is refunded. Quite fun

There's even some really weird ones it allows like Congeal Time and Temporal Bolt. (For the former, I recommend... is it Nulltweaks that makes Congeal Time do a temporal DoT?)
