-% Enemy Resistance decreases enemy resistance, but only if < 100%. It only applies to any damage applied by the user.
- When present on two weapons, the percentages of both are summed and applied to the enemy. [1] [2]
- It does not apply to damage applied by pets summoned by the user (including sentry traps), with the sole exception of Hydra.
Decreasing enemy resistance can have a significant impact on damage, particularly after removing an immunity. For example, casting level 7 Lower Resist decreases Resist 100% to 90%, so the immunity is removed but only 10% damage is applied; -15% Enemy Resistance decreases it from 90% to 75% to increase damage from 10% to 25%, multiplying it by 2.5 (25/10); another -25% Enemy Resistance decreases it from 75% to 50% to increase damage from 25% to 50%, multiplying it by 2 (50/25) or 5 (50/10) overall.
The table below lists multipliers of damage (or effective life) as resistance decreases (or increases):

Of course it can result in Resist < 0% as well, decreasing it to the floor of -100%.
