Thoth pens the names of his fallen opponents in his book, recording their weaknesses. After killing 30 enemies, Thoth gains a stack of 4 Magical Penetration. He unlocks a new stack every 4 levels, up to a maximum of 5 stacks at level 17.
Kills for one Stack: 30
Penetration: 4 per Stack
Max Penetration: 20 (5 Stacks)
The passive for Thoth allows him to get early penetration and allows him to be a major threat to tanks throughout all stages of the game since of the damage he can pump out. I make sure you get these stacks as quickly as possible either by killing enemies or hard-farming the lane.
Thoth raises into the air, ignoring the Basic Attack Movement penalty and conjuring 3 Hieroglyphs. His next 3 Basic Attacks pass through Enemies and apply Ability Damage instead.
If these attacks pass through the Glyph of Pain, their range is increased by 30.
Ability Type: Buff
Damage Per Shot: 35 / 55 / 75 / 95 / 115 (+25% of your Magical Power)
Glyphs Spawned: 3
Cost: 60 / 65 / 70 / 75 / 80
Thoth's main damaging ability is through this. The 3 glyphs do alright damage on their own but when combined with his Glyph of Pain the damage can really stack up.
Evade and Punish
Thoth dashes in the direction he is currently traveling. After dashing, for 5s Thoth's next basic attack instead fires a magical projectile at the target which stuns and deals ability damage, stopping at the first enemy god hit.
If either the Dash or Attack passes through the Glyph of Pain, their respective range is increased by 30.
Ability Type: Dash Special
Damage: 70 / 110 / 150 / 190 / 230 (+60% of your Magical Power)
Stun Duration: 1s
Cost: 70 / 75 / 80 / 85 / 90
Cooldown: 16 / 15 / 14 / 13 / 12s
This ability is basically a version of Rama's Rolling Assault (Go check my guide on him as well :D)But anyway, with this you're gonna want this on quick or instant casting so you're easily able to dodge abilities or auto attacks if needed. The damage is practically the burst that Thoth has and I always would recommend shooting this through Glyph of Pain when possible.
Glyph of Pain
From his book, Thoth conjures forth a Hieroglyph in front of him. Thoth's ability projectile passing through the glyph receive increased damage, and a range increase of 30.
Thoth and allies Basic Attack projectiles receive a reduced damage bonus, but no range increase.
Ability Type: Ground Target
Ability Bonus Damage: 15 / 25 / 35 / 45 / 55 (+10% of your Magical Power)
Basic Attack Damage: 10 / 15 / 20 / 25 / 30 (+10% of your Magical Power)
Cost: 25 / 30 / 35 / 40 / 45
So imagine you're the enemy just chilling in lane and then you see the wall get brought up. At first you question the decision of him raising the glyph only to realise seconds late he's cleared the wave and chunked you for about half your health. Now the damage this adds onto your basic and abilities allow you to easily chunk plenty of enemies health bars.
Thoth begins summoning pages from his book, up to a maximum of four. When all four have been summoned, he sends them forward damaging all Enemies in their path.
Thoth may activate this ability again to fire the ability early, doing a reduced amount of damage based on the number of pages currently summoned.
This ability can be canceled for a cost of 30 Mana.
Ability Type: Line
Damage: 360 / 430 / 500 / 570 / 640 (+120% of your Magical Power)
Now with this ult is practically the snipe of snipe abilities. Sure Ra's Searing Pain is an instant 700-900 damage but with this you can 1 shot any mage that is missing at least a quarter of their health. Now you must know that you're gonna be screaming "AHHHHHHH!" as you charge it up so people are going to know that you're charging your ultimate move. Also the 30 mana cancel cost is nothing when it comes to late game so just don't worry about it.
