By start he can deal more than true damage going to BOUNS damage if the armor goes beyond 0 and to continue if he land the whole combo is like 2.5k damage at least. And AOE Of couse you need to have skill to land the 5 spells on 1 victim... And for the finnish percentage magic penetration stacks additivelly making it a 64% penetration as he surely be usind Liandry's Torment (15) Sorcerer Shoes (15) and Mr pen runes (19.53 aprox) he would have a roughtly 50 with means that you need to have 140 MR to make himnot dela bonus damage on you. For a melee champ if he does not build MR he lands a nice 30% bonus damage  (aprox didn't do the calculation yet). He is underplayed because his early game sucks his ult is real hard to land with a 0.7 delay and to land that much of damage he needs to CC himself potentially making hima a easy target. Conclusion High riskHigh reward.
