Tempered Steel

By Nemesis A, in Runewars Rules Questions

Ok, sorry if this has been covered already. My question is for the tempered steel upgrade card - since it exhausts when used, is it only a single surge that can be traded for a hit or could you use it for multiple surges during that attack?

A single surge.

It's already a very strong upgrade, it would be incredibly overpowered if it allowed to spend more than one surge.

Thanks. That's how I read it, but it never hurts to be sure.

Master crafted weapons with CI is what your looking for, unfortunately slurm team is the only viable unit for it currently.
