Morde excels in extended fights where you're able to ramp your damage over time with your passive. Conqueror empowers that but dealing bonus true damage with every passive tick.
Triumph synergizes well with Morde's [R] allowing you to come out the other side healthy enough to continue fighting.
Morde's biggest weakness is his lack of mobility and ability to be kited. You need to stick to your target to deal damage and Tenacity will go a long way in doing so.
Coup De Grace is the defacto damage amp choice, especially for Morde as you will be building a few health items.
Second Wind is great for extended fights/trades allowing you to sustain health rapidly over time when combined with Doran's shield.
Revitalize synergizes extremely well with Morde's [W], empowering both the shield and heal portions.
