The return of Dungeon Fighter Online (OPEN BETA PT. I STARTS MARCH 24TH!).

Any way to get a third/fourth hotkey bar? I'm already out of slots and only 17 on summoner.

As Jormungandr said, only 2, & use of commands.

I would suggest setting the Tier 2(lv. 30 summons) on a hotkey due to their commands not matching with T1/T3 (although they aren't hard).

Tier 1(lv. 15) and Tier 3(lv. 60) summons have the same exact commands by default with the exception that lv. 60 ones have an additional left/right before Z.

1st Awakening actives are universally "up up down down Z" by default.

Echev and Louise are basically the same with the initial command reversed.

Sandor and Enraged Sandor are a bit confusing compared to each other, so possibly hotkeyed?

Freet and Aukuso, most people drop these I think, or use to.
