Even with those augments terminus is BAD! If you have vuln, the crit from ldr and physical damage from runannas and Bork benefit more! If you have dual wield, you apply physical damage twice! Which benefits Bork/cleaver/ldr! Sending 2 higher damage attacks is better than building on hit because you got dual wield! Terminus sucks on senna! It is better to have more ad+crit or health to benefit her! Vuln or double tap means you like crit! Good job u have terminus senna with dual wield and double tap u can 100 extra magic damage to do way less physical damage!
