Island scouting, assault and development

<h2>Scouting</h2><p>Islands are hidden by fog. Sail close and scout with the learned skill. Scouting percentage controls revealed towers, NPCs, buildings and pearl data.</p><h2>Assault</h2><p>Wave one contains defenses; wave two contains NPC garrison. Select living targets and attack direction. After battle the player returns to the sea beside the island.</p><h2>Ownership</h2><p>Victory preserves the deposit while the owner rebuilds defenses and hires increasingly expensive NPCs. Move pearls to the hold and unload at a port. A fully depleted and emptied island disappears and later respawns elsewhere with level-appropriate defenses.</p>
