I purposely held off putting forma into vanilla [Khora] because I couldn't get the build right and refused to waste Umbral forma on a vanilla frame, thankfully I didn't have to wait that long but yeah, I ended up with three Umbral forma's, leaving a single slot to swap out a mod when needed, [Preparation] can be swapped with Strangledome, etc. Now that AoE weapons have been nerfed it was probably a waste to put [Primed Sure Footed] in there since I'm using the [Kuva Ogris] most of the time but I'll keep it there until I find something that I think synergises better since I'm still using it despite the depleted ammo nerf, must admit, I'm relying on my [Tenet Diplos] a lot more than I was and the changes have negated a lot of the farming techniques for clearing a tileset.
