According to the "don't miss anything" guides, I should fight Dantarg as one of my final 3 heroes to avoid missing other content. However, he's camped out in the East Subterrane, which I need to clear to unlock some stuff. How do I get him to clear out?

According to the wiki, I need Water level 26, but Im already at level 28 and I don't see it in the magic school... highest one I see is Water Dance. What's missing? The final boss in this game is way too difficult, I really need this spell. I hate that I even had to look things up, I played this game completely blind, but everything went smooth for me throughout the game until the final boss! (Other things that didnt go smoothly was that some random battles can 1-hit kill me ever since like the first time...

Does the PC version have QOL or do other platforms have qol? can't decide which console version to buy

My favorite one is SaGa Frontier 2, and then RS2 and RS3.

I'm playing the PS4 version and I've been searching online, but I can't find an answer as to how to see what weight armor or weapons have. Viewing equipment in the item menu or equip menu just tells me the name and defense/attack.
