A high Reflective Emanation combined with a high Grim Resilience makes the Shadow Warrior practically invincible
Gold mod Idol works on summons also (Nether Allegiance and Rallied Souls). This will give each minion a spikeshield animation (that cannot be toggled off). Prior to Community Patch 1.60, this also significantly lowered framerate and game performance when several minions were on screen. This is now fixed.
Note that, like all CA's in the Malevolent Champion aspect, casting speed is determined by weapon speed, and can be boosted by weapon lore skills and +% attack speed. Likewise, the casting speed will be penalized by wielding a weapon with too high a level.
Note: In the console version, this Buff will create issues with scrolling in the Bonus Overview. The issues disappear when the Buff is deactivated.
Pros and Cons
Can be modded to reflect almost any combination of the major types of attacks and detrimental effects.
Can benefit party members and summons.
Serious drops in framerate when using the Gold mod Idol + several summons, requires CM Patch to fix.
