Have you ever looked up after a long boss fight to see your armor at 60% shields, and realized that you were never in any danger? Is your blood altar flooded with RF instead of blood? Do you feel like you're "too endgame" to have any challenges any more? Do you occasionally ask yourself, "Where did this all go wrong?"
Look no further, friend. I think I have just the thing for you.
There is lots of damage in the Minecraft modded world listed as "completely unblockable by armor, and can't be mitigated by potions or special effects." But a few mods, which shall remain unnamed, are actively hostile to unblockable damage, and employ all sorts of tricks to cheeze you out of your well-earned death. Well, life is precious because it's short, and my tricks are better. Please enjoy this mod, which makes *certain* that unblockable damage is honored, even in the face of disingenuous armor, shields, or baubles.
