Just your basic leveling guide for Anubis, E max gives you ranged damage, a slow and some good teamfighting.

Passive, Sorrow - Steals Protections and increases Anubis' healing from Lifesteal, stacks 3 times. This ability stacks per tick, and Anubis' Ability 1 and 3 tick twice a second. On top of that you can get multiple stacks per spell on different items, so on a minion wave you instantly stack your passive in 0.5 seconds. Against a single target it takes 1.5 seconds to reach max stacks. Steals 7 protections and grants 33% bonus healing per stack/ 99% bonus healing and 21 bonus protections at 3 stacks. It also reduces all crowd control durations by 33%

Ability 1, Plague of Locusts - Short ranged high damage ability, people really underestimate the damage this does. At max rank it does 570 base damage + 240% of your Magical power over the whole duration. It also ticks extremely quickly to stakc your passive almost instantly. Lasts 3s and makes Anubis immune to all knockbacks and knockups. Against most fighters you can just use this through their spells and avoid their knockbacks. Gilgamesh can't drop kick this!

Ability 2, Mummify - Pretty simple, a skillshot that goes forward relatively quickly. Hit a single enemy god to stun them. Stuns for 2.5 seconds at max rank.

Abiility 3, Grasping Hands - Mid-high ranged AOE damaging spell that also slows. Great for clearing minions and for just throwing at the enemy. Lasts for 2 seconds. This thing deals impressive damage early game, and can surprise people.

ULTIMATE, Death Gaze - Mid-high ranged straight line damage. What makes Anubis such a damage threat, casting this deals damage ticks 10 times a second. At max rank it does 1290 (+450% of your Magical Power) damage over 3 seconds. This makes Anubis entirely immune to any crowd control however you can only spin in place. This goes through walls and deals damage to all enemies along it's range.
