Metamorphosis

Metamorphosis is an ultimate magic ability. When activated the player transforms into an elemental dependent on their most recently cast spell. While transformed, combat spells cost no runes and damage dealt is increased by 50%. This ability lasts 20 seconds. Although no runes are consumed, players still need to have them in their inventory.

The spells' counterparts in Ancient Magicks do affect this ability and their damage is also increased by it. Gale spells turn the player into an air elemental, Rock spells for earth, Bloodfire spells for fire and Ice spells for water.

It is impossible to teleport or perform emotes while transformed.

The ability is useful when facing multiple foes, such as during slayer assignments. While transformed, it is possible to perform a critical hit of over 3600 with air surge.

==Comparison to Beserk Beserk is the melee counterpart of Metamorphosis.

 * Same duration

Disadvantages

 * Lower damage boost (150% vs 200%)

Tactics

Countertactics

 * Outclass your opponent in terms of damage by using powerful abilities such as Rapid Fire, forcing them to eat and thus rendering Metamorphosis useless.
 * Simply stunning them can avoid to get damaged.
 * Reflect could both halve your damage received and damage your opponent, leaving them in a dangerous state.
