That said, Herc axe is usually a safe bet to invest in due to it being a likely choice in high power teams. Its burst effect being a strong defense debuff is desirable (well, Herc bow would have that too, but axe is the +elem one) and Hercules herself is great.
And since Arthur can equip axes too, gotta wonder, would Arthur even use her own relic weapons over Herc's axe? You trade in Arthur's relic weapons' burst effect (self only +10/25/35% assault buff) and either (+30% element and reducing her nuke's cooldown from 6 to 5 turns) or (+HP and making her atk buff raise assault by another 20%) for Herc axe burst effect of -15/20/25% def debuff.
(Not gonna lie, at first glance, Arthur relics' burst effect looks terrible next to Herc's)
And you do need to get the relic weapon to 1* to actually get a burst effect. So that's 60 regalia.
