The tree itself is a Chaotic zone, which is a PvP area; so players will be able to attack you and you will be able to attack them. Be careful, death risk is very high as high-end players are frequent in the tree, mainly so they can kill the Tier 5 Naga. Tier 4 armour is strongly recommended.People generally stand in the top of the tree which is the hotspot for Tier 4 and Tier 5 Nagas. Always be wary when farming, because players (and mobs!) can really sneak up on you! Also remember that when you kill a player, you will get the Chaotic Alignment
Chests and LootInside the tree, there are a large number of loot chests scattered around, and they can contain Tier 2, Tier 3 and maybe Tier 1 loot. This includes weapons, armour, enchantment scrolls, gems, potions and food! Chest loot varies what floor you found the chest on, for example if the chest was found on the top floor, it would be likely to be Tier 3 loot or possibly Tier 4 loot. Drop rates from mobs are the same as anywhere else, there is no exact revealed drop rate for any mob. Note that Tier 4 and Tier 5 drop rates are much rarer.
