There's one split hero per split combination. At this rate, there should be one for each of them in not too long. Attached is the list of used and unused split heroes. Anyone care to speculate? KF/FS Tremir Craghide KF/SP Spirit of the Peaks KF/ST Jek the Silver General KF/UD Ash the Bandit Prince UD/FW Matriarch Sarinda UD/FS Jyx the Shadesworn UD/SP Zoalt the Sky Serpent UD/IS Hraken the Bloodbow UD/SL Kiergana ST/FS Shardseer Argol ST/SP Zeventrech the Last ST/IS Mosharn the Barricade IS/FW Magnus the Fallen SP/FW Voil King Ruubgaal SP/SL Garin the Sharpfang FS/FW Timothy the Vile FS/SL Mangleshell __________________________ FW/SL KF/FW SP/FS IS/FS IS/SP IS/SL ST/SL ST/FW UD/ST KF/SL KF/IS
FW SL - Undead dragon, probably a Skeleton/Dragon. IS SL - Since we have half skeezick, perhaps a half draksar. ST SL - A Lonx/Jakei riding a dragon, or perhaps a beast of some kind. KF SL - A beastlord that works with snakes, since both factions have snakes.
I will list possible themes based on lore and/or mechanics that a split hero could cover/develop: FW/SL Death benefit and charge based bgs, bg would work around doctor + death charged mutation units and rite champions. Currently timmy is the best for this one. There is also minor dread split support. KF/FW Spirits could be interesting, treefolks also. SP/FS Something able to support electricity/para strike, knockback and semiaquatic would be ideal IS/FS Some construct/relic/equip synergy to exploit engineers in fs, salamans, and the combination of tortun land cannon, armory, forge hammer and horn of order. There is also paralysis module with bane blast. IS/SP it could be storm clan barbarians synergy with electricity and paralytic strike + bane blast, or construct synergy to take advantage of overcharged, calcified lurker and metallic slag. IS/SL Skeezicks would be my first choice, (Raxar, rebel skeezick general) if not, some paladin split support, to take advantage of a pretty developed slection of champions in SL ST/SL yetis is good option, another would be dragon to support tailwind skywings ST/FW something with foment and frost amp would be lovely to support skeletons/frost amp. UD/ST Beasts is a safe bet, and arthropods maaaaybe. KF/SL mutated garu or more treefolk sand synergy KF/IS centaur barbarian
As far as my guesses: FW/SL: Some kind of undead super-mutant. KF/FW: Either witches, or more likely, D'elim. SP/FS: Lightning, elemental, or beast support. IS/FS: An FS paladin. IS/SP: Lightning and Construct love. IS/SL: Skeezick, there are no other options. ST/SL: Strig Dragon-tamer. ST/FW: Hoarfrost, maybe an undead Jakei or Lonx. UD/ST: This is a hard one. A flame corrupted Jakei? Maybe a Jakei-Nefari offspring? A fire elemental that's been put out? KF/SL: A cactus hero. KF/IS: A super barbarian centaur.
FW/SL Some sort of Draksar necromancer. Charges/Mutation synergy could be interesting. KF/FW Spirit or Witch synergy would be cool to incorporate the Warwitch or Ghost Stalker. Treefolk could be worth looking into as well, but with only one FW treefolks it is unlikely to be worth basing something on. ST/FW Skeleton Hoarfrost seems obvious, to mesh with the 2 FW Hoarfrost champions.
I think i would be most excited for KF/IS that has always been a favorite spit of mine and if they flesh out the centaur them that would be awesome!
