Honestly Renegade would really fit the bill for a minion oriented type skillset. Kalla summons as they currently are are kinda awful, they're stuck in this weird limbo of being wells and actual minions and it just leads to scenarios like them getting CC'd and not doing anything, summoned to only die immediately or nobody actually standing in their AoE's so they don't end up doing anything in the long run or straight up not summoning them at all because of terrian issues. I'd say just rework the Kalla skills into full fledged minions, that way they're more useful and you can have an actual spooky charr warband fight with you, it's a win/win.
