Here's some new-ish information about the upcoming expansion.
Armourmaster Haku- Haku's missions seem to be "grab spirit; return to me." The spirit may give some sort of buff.
- He does armour crafting. Some mods: +35-64 maximum life (costs 3 chaos); +4-8% weapon elemental damage (costs 5 chaos); 55-68% increased armour (costs 3 alchs)
- His hideout's tileset is based on the Coast.
Upon reading some Reddit comments, there's possibility that Haku crafts defensive stats on armour(but ele damage?) while Catarina does caster stats, which leaves another master to put weapon stats on armour.
Vorici, Master Assassin- Vorici's mission may be based on attacking rogue exiles.
- He does socket crafting. Some mods: Six sockets (cost 350 jewellers); Six linked sockets (cost 1500 fuses); At least one red socket (cost 4 chroms)
- His hideout's tileset is based on the Slums.
Loremaster Elreon (Gamespot link)
- Elreon's missions are based on defending relics from waves of monsters. The relics may also require a certain number of enemies to be killed near it and may also provide buffs.
- He seems to do jewelry crafting. Some mods: 1-2% mana leech (costs 2 chaos); 10-20% increased energy shield (cost 8 chaos)
- His hideout's tileset is based on the Library.
Catarina, Master of the Dead AND Rampage League (MMORPG.com link)
- Catarina's missions are based on killing certain enemies and bringing their raised corpse back to her. Possibly defending limb-towers, too?
- She seems to do intelligence armour crafting. Some mods: +26-30 intelligence (costs 5 alchs); +35-44 maximum mana (costs 5 alchs)
- Her hideout's tileset is based on Fellshrine Ruins.
Rampage league sounds fun as hell.
