Jr. Lava Slime talents and the best ones to take

Jr. Lava Slime can roll 9 different talents. When the pet hatches, 9 talents are picked at random from this list (the same one can be picked more than once; see how many you can get). You unlock them with talent points, one every 2 levels (5 in total at the max level of 10), so the basic idea is to unlock the 5 strongest of your 9. The table lists each talent with its effect per point, from the game data.

TalentEffect (per point)
Asserting Dominance +15% damage against bossesAffects the pet itself
Breaking Skin +30% critical hit damageAffects the pet itself
Burning Anger +40 burn damage applied on hitAffects the pet itself

How many talents can Jr. Lava Slime get? Can you take the same talent 5 times?

  • You unlock 5 of the 9 rolled talentsWhen the pet hatches, 9 talents are rolled from the 9 candidates above. The pet earns a talent point at Lv.2, 4, 6, 8 and 10 (5 points at the max level of 10), and each point unlocks one talent.
  • The same talent can be rolled more than onceEach copy in the 9 can be unlocked separately, and the effects add up (two copies of the same talent give twice the effect).
  • Five of the same talent only works if it was rolled 5+ timesWith only 5 points, a sixth copy is wasted; with only 4 copies, the fifth point has to go to something else.
  • The 9 rolled talents never changeA talent reset (200 Ancient Coins) refunds your points but keeps the same 9 talents. To get a different set, you have to hatch another egg.

How many copies of the same talent end up among the 9 (an estimate that assumes each of the 9 candidates is equally likely on every roll; 1.00 copies on average).

Copies of the same talentChance (estimate)
0 35%
1 39%
2 19%
3 5.7% (about 1 in 18 pets)
4 1.1% (about 1 in 94 pets)
5 or more 0.1% (about 1 in 690 pets)

The game does not publish how likely each candidate is to be rolled, so the chances are estimates that treat every candidate as equally likely. Sources: Explorer's Guide (1.3 Update) p.68 and the Core Keeper Wiki (Fandom) "Pets" page.

Which Jr. Lava Slime talents to take

Most talents of an attacking pet strengthen the pet itself (see "Affects the pet itself" above). Talents that raise its damage or apply status effects add the most to its fighting power.
