Epic Fight Guard Fix

Weapons with no guard of their own no longer "guard" with an idle pose

• guardfix used to force Epic Fight's guard skill available for any weapon, even ones that have no guard animation or guard stance defined at all (e.g. SimplySwords Epicfied's Emberlash). Holding right-click on those started a guard (with movement slowdown and damage negation) while the character just stood in the idle pose.
• Now the no-shield guard is only forced on for weapons that actually define a guard pose. Weapons without one behave exactly like vanilla Epic Fight (no guard), and anything Epic Fight itself allows to guard still does. Shield + weapon combos are unchanged and still use the shield-raise pose.
