You’ve encountered one of Vi’s Roses.. This counts as a rare creature encounter for the purposes of levelling, but does not count as a Random Event for levelling or MP. There will be no further admin/re intervention. You can post a link to this thread in the character updates thread if you pick the rose, to have it added to your inventory.
Vi's Roses (rare): A beautiful crimson flower with thorns of deep gold, it is rumoured that these roses are coloured with Vi's lifeblood. When planted, they have the ability to cleanse the area around them.
