I have Death Sentry maxed out and with gear my Fire Blast is lvl 19. My Death Sentry is only shooting 6 times. Shouldn't it be 11 since the base is 5 shots and the Fire Blast synergy should give it 6 more (1 per 3 lvls of FB)?
It seems I'm only getting a bonus from the hard skill points in FB (4) and not the 15 I have from gear, is this how it's supposed to work?
Druid summoning bonuses aren't synergies, they're just benefits that existed previously (like Holy Shield's bonus to Smite), and Prayer is the only exception I know of, allowing it to be called a pseudosynergy, but formal synergies only use skill points spent, or 'hard' points, synergize their respective skills. For other skill bonuses, most push abilities into the scaling area which still make them invaluable, and allowing them to synergize would mean people would continue playing as they did before .10 - placing one point here and there, using each as a magnet for +skills.
