We have this already? This mechanic is linked with Skill System but if you manually put "5" the Grimoire adds the 4th skill instead.
For now, I only use packet spammer, but in long runs (Like Aranx) it seens helpfull.

I did this and seens to work fine! Ive used Honor Potion


"Skills": {
"$type": "System.Collections.Generic.List`1[[Grimoire.Game.Data.Skill, Grimoire]], mscorlib",
"$values": [

{
"$type": "Grimoire.Game.Data.Skill, Grimoire",
"Text": "5: Potionname",
"Index": "5"
},
Maybe we can make a plugin to grimoire? Dont seens hard
