[1.4.8] Piercing Shield blocking lava

[Stuntofthelitter]

Zeyphor discovered an amazing error. Blocking while on lava floor with Piercing Gaze equipped can result in this error:

Code: Select all

Lua Error: /data/general/objects/world-artifacts.lua:6607: attempt to call method 'canBe' (a nil value)

canBe doesn't seem to play nice when checking this manner of source.

and it probably also tries to petrify every trap in the game and the damage that kills the temporal warden and/or paradox mage in the TW-only daikara event on level 3; and be sure to account for spectral shield too, and maybe even tree of life(vs. undead) too

i also wouldn't be surprised if the shield, black mesh, bugs like that too, as well as shields that do non-aoe damage when it blocks damage that would be otherwise taken
