Good synergy: Necrosis worms Short lived units Lumbering Replicate and cloning / splitting units Leverage units (although it would be better if leverage worked as a %?) Death nova units On deploy effects Death pact units Drain units Vengeful units Cheap units (can give free rune draws essentially) Zombie rotwrapper Rite of healing Damage / debuffs over time abilities, if duration is fairly long Bone circle staff Vitality creation if using cheap units to gain utility from rune draw advantage /#of playable runes Setback Aspect of death Doom Ammunition units Death harvester Soul sift Self destruct units Lich return from dead mechanic Riders such as general korisen Rite of healing, killing your own real units, especially for altar Body guard Decay (spell) Desecration (spell must hit your own unit to be cast) Nearly Anything that self damages such as exertion Sabotage skills Negative synergy- Healing Summons Scaling abilities such as escalation or this Thirst for battle (technically you won't want to sacrifice these units early) Surge (early game u want to be cycling units to give yourself map precense, generally speaking) Dead magic zone except on central pieces Shields Hex Debuffs which stop the enemy from killing you (but debuffs which hinder the enemy to survive, such as decay or inhibiting touch) Gravetend, reanimated, necroweave Etc etc. Point is there are many runes which have very little synergy with the FW bonus. Nearly all basic skeletons and zombies have little to no synergy. All vampires actually have negative synergy. Witches have extremely little synergy (seriously elsari coven is weak af and does NOT make up for negative synergy. A few witch spell are admittedly decent but they also have negative synergy like healing, and again, elsari coven is so pathetic. ) Can we please rework zombie racial entirely (their swarm ability is very weak, and there is no reason to deploy must zombie apocalypse units otherwise), FW vampire as a theme entirely (give them reworked spells or a spam unit, and a racial with better synergy (maybe a toggle self damage life siphon that costs 0 nora?) And give skeletons without synergy a racial, such as dying produces a short lived risen warrior? FW really needs more synergy with their current bonus.
