Sinister Maelshyvean hierophant
The hierophant is nothing more than the befouled remains of a fallen priest, corrupted and turned to do the bidding of a false deity. The creature is entirely shrouded in tattered black robes, concealing all about it but its vague shape.
A sinister Maelshyvean hierophant surges with a bloody crimson aura as a writhing ebony tentacle lashes out of its robes and strikes out at you!
The barbed tentacle coils viciously around your left arm, crushing bone and ripping flesh with a good strike!
Simple summary: This creature caps at about 650-700. Detailed summary caps are below:
Evasion basically stops at 700-720
Shield/armor still exp slows at 720
Stealth exp slows at 700 and stops at around 720.
Weapons slow at around 625 and stop at 700.
You can hit them with 350-400 in TM and Debilitation magic, but you have to raise your 'spell integrity' high due to their natural immunity to spells (evil).
A good suggestion is to have all mental stats to at least 60. Their spells will kill you quickly if they hit you and usually will result in a stun.
Compared to other creatures of similar difficulty, these creatures have high parry ability, making it more difficult to hit with melee weaponry.
