Earth Ultima II

Like other Second level Ultima Spells, excluding the Air Ultima II, Second level Ultima Spells are not able to cast.

The Earth Ultima II is an uncastable spell, and the most powerful earth spell in RuneScape. Despite uncastable, it can be witnessed by fighting Gill in Ultima Destroyer form (or Zar.Gerssick in any forms). It is composed of an earth missile which is two times larger than Earth Surge and spawns 5 earth surge missiles then followed by Quicksilver.

Quicksilver
Like Fire Ultima II, the main missile will not move until all surges were spawned and exploded on the player, the main missile is larger than a player, it only has 2 pieces of earth holding by the core gravity instead of three. The core color is orange instead of green.

Since the battlefield is exactly equal to 9 dungeon rooms (during the fight with Ultima Destroyer, Astral trio & Gerssick) the caster will say "TAKE SCIENCE!" and will rise a formation like that of Solar System (only the 'planets' are 5, which the planets are surges) each planet spins at the main missile at two seconds to complete the revolution. That means after the caster casted the formation, they will revolve to the main missile first. Afterwards, each planet will go away to their orbit (Note that the surges are flying away from farthest to nearest), a gray version of the main missile) Fire surge flies away to the player, and it returns to touch the ground he player stands. The grey goo scatters as if were making a quicksand, since mercury is a dangerous substance when inhaled, the player damages by 10 constantly, reducing your run energy to 0, inability to walk or run, and damages again by 30-90 lifepoints.

The spell lasts for 25 seconds. Having Protect from Magic only negates the effect by 5 seconds.
