Making a pretty fun build atm, my testchar is a Beckoner/Tactician. I'm dualwielding Grave Calling with Chilling Grave together with Hand Mortar and have Powder Burns on to confuse myself and have Mob Stance for instantly killing all my skellies. However I'm wondering if it wouldn't be better to be better to go Troubadour for faster Skelli chant. My main concern is me not oneshotting skellies, but also the single skellie from chant having less impact than the ones from invocation.
