Maj'Eyal is full of monsters, and you have learned to befriend them. As a Monstermon Trainer you catch wild creatures in capture orbs, raise them into a team and let them fight for you. Earn the badges of eight gyms, beat your rival and stop the five ancient Primordials that are waking beneath the world.

A new class
120 new monsters with their own art and evolutions, and almost every creature in Maj'Eyal can be caught
More than 1,300 monster abilities
Gyms, trainer duels, ruins, quests and over 70 new items

Visual update of the added monsters
Added extra difficulty settings to balance the harder modes.
80 new monsters: there are now 120 monstermon. The new ones appear from level 14 on.

Expeditions for your monsters
A bed that makes you Well Rested
A slot machine with a jackpot and a rare lucky monster
Grandpa's diary: find the lost pages around the world and read the story of Grandpa and the Primordials.
Five Primordial bosses: they wait behind rifts, each in its own arena. Defeat one and it joins your team.
Stronger duels: trainers and gym leaders now raise their monsters just like you do.
Oswin's Rest rebuilt: the brothers' home is furnished, with an arena, a garden and new quests.
New capture quests: each one rewards a unique Monsterdex.

Sling mastery affects steamguns.
Any check for "am I holding a sling?" will be happy if you're holding a steamgun.
Not tested for anything but holding one mainhand steamgun and using a skirmisher talent. SHOULD work with any talent, but I have no idea what dual-wielding will do. Either it'll error, or it'll be OP.
