Why does Wyrm have an ability to increase its own strength? It can only break subroutines on ICE that has a strength of 0, right?
I always play Wyrm as though you use the ability that gives a piece of ICE -1 Strength as often as you need to get a piece of ICE to 0 strength and then you break the subroutines on that 0 strength ICE with Wyrm. Or, sometimes I use Wyrm to lower the strength of a piece of ICE and then use something like Aurora to break the ICE's subroutines now that it is low enough strength for Aurora to break them, etc.
But am I playing Wyrm wrong? I can't see a reason to increase its strength.
