Yasuo has IE and conqueror, so 30% of his damage is true, the remaining 70% are reduced by 12% from tabi and then cut in half by armor to a final value of ~30.8%.
Conqueror and Infinity Edge are multiplicative stacking NOT additive.
Conqueror converts 20% of all damage to True so that leaves an 80 / 20 split.
Infinity Edge then applies to the 80% physical damage which is 8%
20 + 8 = 28%
Let's say Yasuo crits for 500
Tabi's gets applied to the 500 so it's 500 x 0.12 = 60.
So that leaves a 440 damage critical strike.
We now do 440 x 0.28 to work out the true damage conversion which is 123.2
So Yasuo would do 316.8 Physical and 123.2 True Damage.
This is before calculating any armor or armor penetration items.
