I'm thinking that there should be some way to convert extra pips into accuracy for either the next spell you cast or any card you choose. For example: If you have 5 pips but keep failing to cast storm shark, you can activate a thing to turn 3 pips into maybe +3 accuracy. I haven't completely thought it out, but I think something like that would be awesome.
I think it's an interesting idea and definitely deserves thought on how it could be made possible. There are plenty of times when a damage wizard has debuffs that prevent their high accuracy from being 100% even if it's normally 100% or more...having to choose whether to risk it or use an additional power pip could be a pretty cool option.
There are also a lot of wizards with spells that have lowered accuracy compared to their standard spells, or want to use an off-school spell they lack accuracy boosts for. This would also give them an option to use pips instead of clogging their deck with enchants or trying to pull a TC version at the right moment.
If my balance is sitting on pips and pigsy is going to save the blades on the hitter, it would be a no-brainer to use more pips for the safety of knowing it will definitely cast.
I haven't thought it through thoroughly for balancing it or what percentage boost or how it would affect PvP etc....but I do think it's worth thought and discussion because even with OP gear a battle can be won or lost on whether the debuff is effective or not.
