Here's a rough framework: God identity comes later, right now I'm just concerned about gameplay. It could be Notch, god of cube-things for all I care.

Sekhmet - Physical Tank like Ares, can hit like a truck but extremely limited in CC.
Passive: Battle Cadance: After using her 1, 2, and 3 abilities, if Sekhmet has not used an ability for 2 seconds, the cooldown on her 1, 2, and 3 abilities are halved.

She also has a 1.0 base attack speed that does not rise with level. She has a swing chain of x2, repeat. Her basic attacks switch her stance, and her abilities do not cost any mana.

Also, her sword is 20 feet long. So any ability with a swing has an effect radius of 20-feet, and any stab will be in a 20-foot line.

1: Roll (Offense)
Sekhmet rolls in the direction of the keys pressed. Sekhmet is immune to nothing/slows/roots/cripples/CC while she is rolling. Cooldown: 12 seconds

1: Swipe (Defense)
Sekhmet slashes her claws at her enemies, dealing 20/40/60/80/100 damage (+20% of your physical power) and slowing them by 20/25/30/35/40% for two seconds.
Cooldown: 12 seconds.

2: Impaling Thrust (Offense)
Sekhmet dashes and impales an enemy (or enemies) on her sword, dealing 50/80/110/140/170 damage (90% of your physical power), and if an enemy is impaled, she hurls them aside (standing still while doing so, like Mercury), launching them a decent distance and dealing 25% of your physical power as additional damage. Does not knock them up, like Mercury, so no midair-against-wall shenanigans. Note that this ability's reach is longer than the dash distance. Cooldown: 16 seconds.

2: Overhead Lunge (Defense)
Sekhmet leaps, bringing her sword down in an overhand swing, dealing 60/120/180/240/300 damage (+75% of your physical power) in a line. Note that this is a very slow leap, like Odin's, and the damage is ONLY in front of her. Also, good luck hitting with it. Cooldown: 8 seconds.

3: Great Cleave (Offense)
Sekmet readies her sword (0.8 second delay), before lunging and swinging her sword, slashing once in a 15-foot radius circle and dealing 80/140/200/260/320 damage (+80% of your physical power). Cooldown: 18 seconds

3: Decisive Strike (Defense)
Sekhmet readies her sword (0.8 second delay) to deliver a mighty blow, dealing 9/140/190/240/290 damage (+70% of your physical power) in a cone and crippling enemies for 2 seconds. Cooldown: 18 seconds.

4: Desert's Roar: Bellona roars (standing in place for 1 second), pushing all enemies away from her in a 20-foot radius and his abilities deal 25% more damage, he gains 20% movement speed, and becomes immune to CC for five seconds. Cooldown: 90 seconds

Pros: High mobility, good damage, tanky.
Cons: Little CC, LONG COOLDOWNS, dangerous waveclear, and a lot of her abilities have some sort of delay.
