Vamana: The Size of the Dog in the Fight (Arena/Clash)

Vamana is physical melee warrior with an excellent passive ability to counter physical damaging enemies. Effective use of his abilities allows for considerable burst damage and opponent movement interrupts. Vamana's Clear the Path has both an offensive aspect and an escape aspect, but can be interrupted or negate by enemy abilities (i.e. Odin's Ult, Poseidon's whirlpool). This build guide focuses on Vamana's role in an Arena/Clash mode with team support. I have not tested these builds on Vamana in a solo capacity.

Vamana's offensive combo typically proceeds in the form:
Umbrellarang -> Clear the Path -> Armored Umbrella

The combo above is excellent for catching enemy gods unaware and disrupting their formation. Additionally it sets up Vamana's Colossal Fury, by putting him in melee range of enemies; however, using Clear the Path to enter the fray will mean it is unavailable as an escape maneuver.

COLOSSAL FURY
Vamana grows to an enormous giant. While Vamana is enraged, he is immune to Crowd Control, gains Protections, Physical Power, massive regeneration and his Basic Attacks now damage all nearby enemies. When Vamana is in Colossal form, taking damage from gods increases the duration.
You may cancel his giant form early.

Vamana is a very useful offensive support god. His ability to interrupt enemy abilities and movement with Clear the Path and the slow effect of his Umbrellarang make him excellent for preventing enemies from escape. He can also absorb a significant amount of damage depending on the build and dish out a reasonable amount for a warrior. Early-game is a critical time to use Vamana in a support capacity as his abilities don't really blossom until late-game. By mid-game his defensive build should be nearly complete and you can play a bit more aggressively, but he shines in late-game.
