Any time Janus transitions through a Portal or over a Threshold he becomes aged and wizened, gaining additional Magical scaling on his next ability cast.
Janus creates a portal in the world. If placed on a wall, the portal will create a passage through to the other side of the wall that Janus or any ally may use. The portal may be entered from either side, but closes after 1 use. If placed on the ground, enemies and Janus will fall into the portal, being teleported into the air above it. Enemies take damage upon landing, and are considered banished during the fall.
Janus creates two unstable portals, far too small to fit into, and flings them forward dealing damage to enemies in their path. Enemies hit by both portals take 30% damage on the second hit.
Passive: Janus increases the movement speed of himself and allies each time they go through a portal or over a Threshold (max. 2 Stacks). Active: Janus opens a multi-dimensional rift. Enemies who pass over the rift are slowed, and marked with Phase. Targets in Phase take additional Magical scaling damage when hit by Janus' damaging abilities.
Through Space and Time
Janus blasts a ball of multi-dimensional energy across the battlefield, burning a portal into every surface it encounters within range 500. These portals last 10s, may be used by allies, and do not vanish after the first use. Enemies hit by the energy ball take damage, increasing in Magical scaling the further the energy travels. Janus is immune to Crowd Control whilst firing.
