@Shashi, Here’s an attempt at converting a Fantasy Age Bestiary entry using the Simple NPC creation rules (found on the Green Ronin website as a free download) http://greenronin.com/blog/2016/06/29/fantasy-age-bestiary-pre-order-pdf-preview/
Gatorkin (level 3)
Attributes: Agility 4, Might 5, Energy 4
Defenses: Toughness 16, Guard 14, Resolve 12
HP: 26
Speed: 30’
Favored Actions:
Spear - Might (d20+2d6) vs Guard, triggers Immobile
Bite (Only usable when target is Immobile) - Might (d20+2d6) vs Guard
Throwing Spear: range 30’ Agility(d20+2d6) vs Guard
Swamp Spew (once per encounter): 10’ line Energy (d20+d10) vs Toughness
Notes: Bite can only be used when Multi-Attacking.
When charging, ignore the disadvantage penalty.
Feats: Skill Specialization I (Agility), Multi-Attack Specialist I, Multi-Target I Specialist), Bane focus(Immobile)
Strategy: Stalk their prey and strike hard and fast, the Gatorkin attempts to skewer their prey with a spear and hold them in place whilst they bite down upon them
Not sure how well this is explained but the idea i had gotten from the entry was that they stalk their prey, and either hurl their spear or pin the target down so they can munch down upon them
