Lord Deris

Lord Deris is one of the three elemental bosses found in the Celestial dungeon. He is located in the small room attached to the Earth room in the dungeon. The Earth room requires level 80+ Woodcutting and Firemaking to enter, and the room containing Lord Deris requires a sacrifice of 3 Red dolphins(cooked), 3 Sacrite ores, 15 Marbury logs, all of which are non-tradable, so player must either forage these items from the dungeon(which requires a level of 100+  Fishing, Cooking, Mining and Woodcutting), or alternatively players can receive the items as drops from Celestial earth, water and fire warriors. The second option is alot longer than the first, since the resources are an uncommon drop from the monsters, and they only drop 1 resource each time(3 each time from bosses).

The boss can hit very high with Melee, compared to its Magic and Range attacks, so Protect from melee should be on all the time. The boss also has 3 special attacks which it can trigger randomly, which are Earthquake, Sandstorm, Seed Bombs.

Earthquake
The boss slams its mauls down to the ground causing a small earthquake in the room, pieces of the cielling in the room will start to fall down, if a player is hit by any of the falling rocks, then he/she is dealt 200 damage. This happens three times for each time that the boss uses the special attack, "Earthquake".

Sandstorm
This attack creates a sandstorm in the room, which will last for about 5 seconds, for each second all players in the room will be dealt 100 damage. Also for each second the sandstorm is on, the boss will heal 100 lp.

Seed Bombs
Lord Bascull will throw some 20 seeds in random spots of the room(but not on a spot that a player is currently standing on), if a player runs on top of one of the seeds then it'll explode dealing 500 damage on the player.

Other abilities

 * Lord Deris has the ability to wrap players in vines and stun them for about 10 seconds, the players cannot attack back or teleport away while in this stage.
 * The boss has a protective aura on itself, at all times, which protects itself greatly from Melee and Range attacks, so it is extremely difficult to use Melee or Ranged when fighting him, hence players are advised to use Magic against it, preferably a fire spell, since the boss is very weak to fire spells.
