It's a Combo made out of Reflexive charms, and so it's not obvious and has no Essence flare until I use the only Obvious charm, the perfect defence. Even then, beyond the obviously supernatural nature of my defence, you<em>see</em>nothing. You smell the breeze if and when I use the flurry breaker, and you might<em>think</em>you hear the faint whisper of tidal waves when my character is moving, or it might be just the ocean, or your pulse beating in your ears - and his movements look almost supernaturally graceful, but that's all. The Lunar perfect defence is, well, obvious enough for me, so I prefer to only put some non-visual touches on it.<br/>Nobody says the flare's got to be visual, or non-subtle, you know, or Night Castes would have little use for combos ;). Besides, on p.247 of the corebook is detailed an example of a combo that has no obvious charms and thus, no description beyond suddenly becoming really good at what you do.
