Emerald Warden's Summon Gawain
The Emerald Warden permanently summons his owl familiar, Gawain, who gains in power as he does.
Companion characters tend to be poorly done; in some cases, like Dota's Syllabear, they require full player control, which limits accessibility due to a higher difficulty floor. In other cases, like LOL's Quinn and Valor, the companion is relegated to a piece of VFX and feels insubstantial. Gawain resolves this by being an in-world, fully AI-driven character with simple behaviors: attack when near, heal when low, and cast when surrounded. His independence and strength means Emerald Warden players never feel alone.

Tremble's Terrorform
Tremble carves out a hive, granting him bonuses while he's within its vicinity. He may also teleport between hives.
Terrorform (a pun on terraform) fulfills the fantasy of territoriality. When Tremble teleports to a destination hive, nearby enemies can see the ground rumble and dust kick up. Savvy opponents use the hive's lack of long range vision to set up ambushes, while lone players may find themselves the victim of Tremble's one-on-one killing power. Terrorform means Tremble players completely change map control dynamics for both teams.

Artesia: Essence Projection
Artesia calls down a sceptre anywhere on the map, healing nearby allies and mirroring her own spellcasts.
A relatively immobile caster, Essence Projection is a unique take on map presence. While Artesia is alive, her opponents must be cognizant of her ability to support allies from anywhere. Because Essence Projection will mirror Artesia's skill shots wherever it is cast, it adds an extra layer of frenetic action to any match she's in.

Amun Ra's Path of Destruction
Amun-Ra calls down a meteor in front of him, which falls after a delay. Enemies struck by the meteor are damaged and stunned. If he runs into the meteor, he gains significant bonuses.
The classic issue with melee characters lies in their ability to close the gap. The beauty of Path of Destruction is that it can be used as harassment, but also gives Amun-Ra players great impetus to throw abandon to the wind and just go in. This effect is punctuated by the character screaming "RAAAAAAAAA" as he charges forward.

Lord Salforis's Dark Lord's Presence
Passive. Lord Salforis deals constant damage to nearby enemies, though the damage is distributed among all targets.
By distributing the damage, Lord Salforis becomes increasingly threatening as his allies spread. Opponents must be supremely wary of their surroundings, causing every skirmish with Lord Salforis to be a dance.

Midas' Transmute
Passive. When Midas lands two spells on a target within a short window, he transmutes the target to gold, stunning and mollifying its defenses.
Because the Transmute effect lingers, players hit by one of Midas' spells are wary of being hit by another. This fundamentally changes how players interact with him, and increases the reward for landing successive skill shots.

Monkey King: Vault
The Monkey King jumps over his target, dealing damage to enemies around his landing point.
Fun to use but incredibly difficult to master, Vault plays on the impish nature of the Monkey King character while giving him a litany of mobility options. The jump allows him to clear cliffs, making the position of both him and his target paramount.

Nomad's Edge Counter
On activation, enter a state of ascension. If struck by an attack, the damage is negated and the Nomad counterattacks with a massive shockwave.
Taking inspiration from fighting games, every battle against the Nomad is a battle of wits. The Nomad must time Edge Counter to counter his opponent's strongest attack, while his opponent tries to bait out Edge Counter by forgoing damage opportunities. This creates intensely cerebral gameplay, with each player trying to fake the other out.
