So yea, what about items that could increase their usefulness .
T1: none
T2: a bit stronger with 10% less chance to malfunction(shock) and 10% chance to attain a different attack type.
Ex: the knight could have shadow attacks , elemental attacks (no status due to oilers/quicksilvers e.t.c.) and piercing.
T3: same as T2 except there is a chance for increased health instead of dmg and 30% chance to change attack type.

Any ideas?
