Grenwall

Grenwall are vicious Hunter creatures found only in the forests of Isafdar. Level 77 Hunter is required to catch them. Box traps must be baited with raw pawya meat as they hunt pawya; unlike most other Hunter creatures, bait is required to catch Grenwalls. They offer the most experience of any Hunter creature when caught.

Upon successfully looting the creature, they drop from 18 to 21 spirit shards. These shards can be used for summoning, sold to pet stores in Yanille. The shards dont make a good profit as Red Chinchompas make alot more cash. In addition to dropping their low cost spikes, players can also get random herbs when they loot them (usually above ranarr).

When they attack a pawya, the prey would be hit at a distance along with a strange hissing sound. The pawya would lie, probably dead, on the ground until the Grenwall comes up and eat it, and when examined it was stated the creature was attacked.

Players can teleport close to the hunting area using a Superior locator.

Like pawya, upon Dismantling or Checking the box trap, bait will be lost although sometimes when checking a boxtrap containing a grenwall, you could possibly get the bait back along with whatever loot you get.

Strategy
All elf hunting creatures will either run or hide themselves when players are near them, so they should make sure to run a few steps away after the trap is laid.

Jagex also specified that due to the magical influence of Isafdar, Grenwalls are not fooled by the use of camouflage gear, such as clothes made from the fur of hunter creatures.

The best method of hunting Grenwalls is to catch them in combination with pawyas. Players should take a Fruit Bat familiar with at least 100 Fruitfall scrolls to a hunter spot that contains both Grenwalls and Pawyas. Surround a Grenwall spawn location with three traps (baited with Raw Pawya Meat) and use the remaining two (baited with Papayas) to hunt pawyas. Continually cast Fruitfall to replenish the supply of papayas and if necessary bait 3 traps, instead of two, with papayas if Pawya Meat supplies run low. Bank at Lletya when you have a full inventory of herbs. This method will enable you to obtain roughly 1k Grenwall Spikes per hour and approx. 100k to 150k worth of high level herbs.

Note: Dropping herbs and 'camping' with multiple fruit bat pouches is not a highly effective training method. This will only gain you 1-5k hunter experience per hour more than banking them and about 50-100 more spikes per hour. For faster experience, it is recommended to take three Hunter Potions (4) with each trip.
