The Weakest Summon? Sorry, I'm the Summoner!

[Game world for all + summoning legion + strongest talent + no burdens + no heroine] A different space full of monsters appears in the real world. In order to fight against the monsters, humans awaken and become professionals. You said you have awakened your S-level talent and are about to take off? You said you have an SSS-level talent that no one can beat? Sorry, I don't know what level my talent is. I only know that the SSS talent is just a way to go for me. [Taboo Amplification]: Unknown level exclusive talent. Level 1 Amplification: You can add a small characteristic to bound items or skills at no cost and upgrade it by one level. Level 2 Amplification: Spend certain resources to add a major characteristic to bound items or skills and upgrade them by two levels. It can also be used to unbound items... Level 3 increase:... What? Do you think talent is useful? The summoner is a sewer? Sorry, summoner is the strongest profession from now on, because I am the master of summoning! I will be invincible!
