The problem
Being a 1v1 BP is kind off bad at lower levels. The grind is a pain. You use a ton of food if you dont have stonehand active. But as 1v1 stonehand has a duration of 1 to 2 minutes. This way you either have to cast it a lot or spend a lot of food. Same issue with STR based Aoe BPs. While not game breaking, it does end up being frustrating and could use some QoL.
The solution
Make stonehands duration scale with both STR and INT. Skills like burst crack already incorporate a scaling system based on the formula (STR * 4.4 + INT * 1.4). Therefore, it would be beneficial to implement a similar scaling mechanism for stonehand. Currently, stonehand's formula relies solely on INT, but a suggestion would be to modify it to (INT * 2 + STR * 1.5) for a more balanced effect. This way INT still provides the highest duration of stonehand, however 1v1 BP's and STR AoE BP can level with lower food costs and 1v1 BP's in dungeons can also AOE and provide stun without having to recast stonehand mid AOE's
