Just a suggestion here but I LOVED D:OS and also always opt for necro's
.
That being said summons were way OP in the first game. Someone said that Larian said SM would allow two summons...if they are as strong as before that'd make sense.
I have a suggestion to help that.
Maybe instead of using mana the SM could use his HP to summon however many units he can afford HP wise. Maybe he pays a % of the units HP and doesn't get that back until the fight / encounter is over.
Alternatively / additionally could have the summons linked to his HP so that if they die or take dmg he takes dmg. I don't particuarly love this idea but I think this could be a cool feature. Super stoked to see what Larian does with this.
