It would be more efficient if instead of displaying a '0' numerical value for fully resisted skills and spells there was a more obvious display.

My first idea is that we could see 'Resisted!', 'Null', 'Half', and such messages appear. That would also allow players to figure out elemental weaknesses much easier.

A second idea is that we could see coloured floating battle text. For half resists the number could display in yellow, for full resist in bright red. The idea is to differentiate between instances where you're doing less damage and where the enemy is actually resisting.

A practical example of why this is needed is from when I first started as a CON/THM about a week ago. I used Scourge and Banish more often, although they drained my MP, because I thought Water just wasn't as strong. The real reason was that Funguars are resistant to Water elemental damage. I didn't know that at the time because it just showed numbers with no difference between a full hit and a partial resist.
