Following the thread about the "Aggro icon" in the other forum.. I've read about more information about enemies being shown to the players..
Now I would like to propose, why not making it so it would be shown by using a Scan or Libra ability or magic and a stackable item with the same effect (Bestiary)..?
Just like the old single player Final Fantasy titles.. the spell could get resisted and display limited to no information depending on a mob's level too high or either a NM..
For example, this is how I would make it work..:
Information shown about a Too Weak monster..:
=== Wharf Rat ===
Level: 1 / Too weak
HP: 720
MP: 230
Race: Rodent
Resistances: None
Weaknesses: Fire / Thunder / Piercing / Slashing
Aggressive: No
Information shown about an Incredibly Tough monster of 10 levels higher or more than player..:
=== Ahriman ===
Level: 65 / Incredibly tough
HP: ?
MP: ?
Race: Floating Eye
Resistances: ?
Weaknesses: ?
Aggressive: Yes
A brief hint about how to fight the monster would be also shown like: "Uses powerful area attacks" or "Attack the horn to expose its weak point" for example, know what I mean..?
In case of complete resist.. the player would just get a message like: "The Ahriman resisted your spell/item." or rather "You are unable to determine the Ahriman's strength"
Beside with leveling, to make information about an IT monster completely available, the player would have to fight it and discover personally it's weaknesses and resistances by using various attack and elemental magic (in a party if one uses an effective attack, all members will be aware of it in their personal scan results).. and if he manages to win, also HP and MP will become available.. you know, little by little with experience..
Scan, Libra and Bestiary would not draw aggro from the targeted mob..
If the scrolling text seems too much, I think "Race" and "Aggressive" could be gotten rid of.. race is probably evident once you get to know the monster.. and for the aggro well, we already have the aggro icon (if it doesn't get removed).. so that makes it two lines less..
