Creature

From GuildWiki

A creature, in terms of game mechanisms, could be any object with a non-depleted Health bar, otherwise it would have been called a corpse.

[edit] Upon death

Quite naturally, only corporeal creatures leave a corpse behind them (not all of them are exploitable though). While spirits only grants half of the normal benefit for Soul Reaping upon their destruction (among other numerous differences)... leaving a doubt about their real essence (as full-fledged creatures).

[edit] Notes

• Spirits issued from Nature Rituals generally affect all non-spirit creatures within their range.
• It's common that beneficial and non-damaging skills do not affect spirits at all, even if stated creatures, foes or allies in the skill description.
• Neutral wildlife is non-targetable (and don't appear as minimap dots) until angered but are still part of the big family.

Nearly every creature encountered in the game can be found in the Bestiary.
