@SMASHING GUY Nope he's just stronger than Eochaid now
Spoiler!
Reread the novel and yes he killed Eochaid only after utilizing Claiomh Solais's full power he even said he can only use it for a few seconds the reason he complemented Korin was because Korin was able to go toe-to-toe against him in pure skill and eventually overpowering him, Eochaid was strong because he was the user of Claiomh Solais in the last iteration but without it he's just a bit weaker against Korin
@SMASHING GUY It's not that you remember their names but you only read some texts, if you read a novel you visualize everything happening while reading and can easily remember anyones name. Not forcing you to read the novel, if you don't want to then don't just recommending it just in case you want to read it
