Lizard~ No move speed bonus. Brown lizard has fireball and is war|war. Grey lizard is unlocked at 15, is war|blm and has snowball instead. Unlocks bugard at 30.
1- Fireball/Snowball (100tp): Pretty weak, AoE fire/ice damage. Can be used from a decent range.
10- Secretion (50tp): Evasion boost. Lasts 3 minutes.
20-Brain Crush (130tp): Physical damage + silence, ok damage.
30-Blockhead (150tp): Listed as doing 200% physical damage + knockback, haven't tested yet.
Bugard~ +50% move speed. Blue box due to size. Havn't leveled this yet.
Raptor~ Bought for 3k infamy. +75% movespeed, whitebox (due to size??) The default skin is the original blue/white one, a second green skin unlocks at 30. Both skins are war|war, and have the same stats/moves including thunderbolt. Unlocks eft at 30.
1- Ripper Fang (100tp): This is listed as doing 200% physical damage, but it does more like 4x damage of an autoattack. Extremely strong/efficient attack.
10- Chomp Rush (100tp): Physical damage + slow. Game doesn't list it, but seems to be 2 hits. Much weaker than ripper fang.
20- Scythe tail (130tp): Physical damage + stun + knockback. Weaker than the other moves.
30- Thunderbolt (130tp): Cone thunder damage + stun. Haven't tested yet.
Eft~ No move speed bonus. Initial eft is war|war, tarichuk unlock at 30 is war|blm. Doesn't unlock any families as of 30.
1- Toxic spit (100tp): Poison, can be used from long range. The effect was really weak when I tried at at low level, might scale with level or something?
10- Nimble snap (170tp): 3 hit physical damage. Does extremely good damage when all 3 hits land, better than ripper fang, the TP cost makes it much less efficient thou.
20- Numbing noise (100tp): Cone stun. No damage.
30- Cyclotail (130tp): AoE physical damage, haven't tried it yet.
Insticts, all unlocked at 30:
Lizard 1(2)- hp+1% vit+5 def+20
Raptor 1(2)- hp+1% attack+5 haste+3
Eft 1 (4)- int+8 mdb+3 fastcast+4
The auto-attack strength is also different between the mobs. Raptor hits much harder than lizard, eft is between them somewhere. Raptor doesn't hit slower to make up for it or anything, it's just a much better melee it seems.
