Tabbris is the Quintuplet of Hell in my Quint Series.
Infernal Scars: Tabbris' basic attacks on enemy champions mark them with "Infernal Scar". The Mark is refreshed whenever Tabbris deals damage to the target. Critical Strike Damage is increased by 50% on target's with infernal Scar
Abyssal Power: Tabbris has 250 Abyssal Power upon starting. Auto attacks use 50 Abyssal Power and killing units gives him 75 Abyssal Power. Upon reaching Max Capacity, He gains the buff "Abyssal Corruption". If Tabbris does not have any Abyssal Power then he uses 50 health for the attack. This attack will not deal critical strike or on-hit effects.
Abyssal Corruption gives Tabbris 120% Bonus Attack speed and separates his auto attacks into 3 damage instances that can critically strike and deal on-hit effects separately.

Tabbris' next attack on a champion for the next 10 seconds, this attack will not inflict Infernal Scars, will imprison them in an area for a small duration. This duration is increased by 1 second for each Tabbris exclusive debuff currently on the target. if the target dies while in the area, the cooldown of this ability is refreshed. The Prison collapses upon Tabbris' Death.
He has main Waveclear in the form of his Q and W but not through Auto-attacks.
Why not his Auto-attacks?
His Auto-attacks are mainly used for last hitting unless you like to waste 50 Abyssal Power on an AA that doesn't kill an enemy. Runaan's will not increase the cost of the auto-attack which gives it a possibility of giving him AA wave-clear but the bolts do not synergize with his Abyssal Corruption Buff
Q and W?
Yes, Even without Mana, This ADC uses his spells as his main source of wave clear, making him useful in freezing or pushing a lane.
Tabbris is a Caster Crit ADC
We have had a few caster ADC in the form of Miss Fortune and Varus. The Unique Thing about Tabbris is that he would benefit so much from essence reaver if he had mana. You can still build this item on him but he has no mana to speak off so good luck with that.
Telegraphed Plays or Mind Games?
The plays Tabbris can do is incredibly telegraphed, what do i mean by this? If Tabbris harrasses a champion with an auto-attack. you can be sure that he might do something like an all-in. Why? He just wasted 50 Abyssal Power on Harass, He will have to make it worth his time for doing that such as auto-R combo into support cc then all in.
He synergizes more with CC supports.
As much as Tabbris can have a healing support as partner. He does need his partner to have some sort of CC to keep them still for a full combo.
