After defeating the dungeon ten times and spending my whole day here, I gained thousands of goblins and ten goblin bosses with thousands of cores and tens of skills but they are all F to E ranks.
I got one or two skills suitable for me.
[Berserk]
-Rank: E
-When cast all the stats of the caster will increase by 2 times and will feel more anger and rage towards the enemy
-Needs some mana to activate and lasts for 1 minute
[Energy Defense]
-Rank: E
-Creates a barrier of mana around the caster
-Takes mana to activate and lasts until it is broken
-Can only block F-rank attacks or E-rank attacks at most
'These are goods.'
After that, like yesterday, I sold my cores, earned some thousands of dollars, and have more than one thousand cores as spares. I am thinking of consuming them but consuming many cores at once isn't that good.
So, I am putting them off for now. And I am not putting those cores in my wristwatch storage but the stomach of my summons.
