protip: your swirling sword pet can have some stuff assigned to it . so if you cant assign olerons to it. assign something onyour weapon.
also you can use 2 beronath shards . just need to be spamming 2 buttons to attack. it works great. (2 x 7 counters)
finally, if you have the nemesis relic, that pet can also be assigned some stuff
any pet that is “scales with player bonuses” is basically an extension of the character, so you can loadthem with heals or whatever. its pretty sweet.
