Grenwall

Grenwall are vicious hunter creatures found only in the forests of Isafdar. They feed on raw pawya meat.

They are Hunter level 77. Box traps must be baited with raw pawya meat. Bait is required.

Their spikes can be sold to the hunter stores in Yanille and Nardah or used as an alternative for Arrow shafts. You can even get random herbs when you loot them (usually above ranarr). All elf hunting creatures will either run or hide themselves when you are near them. So make sure you run few steps right after the trap is laid.
