You draw upon your elven link to the wilderness to change the coloration of yourself and your equipment to match that of your surroundings. This grants you a +4 circumstance bonus on Stealth checks and allows you to make Stealth checks without cover or Concealment, but only while you move no more than half your base speed or less. If you move more than half your base speed on your turn, you gain no benefit from this spell until the start of your next turn. If you attack any Creature.

For purposes of this spell, an attack includes any spell targeting a foe or whose area or effect includes a foe. Exactly who is a foe depends on the invisible character's perceptions. Actions directed at unattended objects do not break the spell. Causing harm indirectly is not an attack. Thus, an invisible being can open doors, talk, eat, climb stairs, Summon monsters and have them attack, cut the ropes holding a rope bridge while enemies are on the bridge, remotely trigger traps, open a portcullis to release attack dogs, and so forth. If the subject attacks directly, however, it immediately becomes visible along with all its gear. Spells such as bless that specifically affect allies but not foes are not attacks for this purpose, even when they include foes in their area.
