Pixelated 'Start Battle' Button with Crossed Swords

"Design a pixelated 'Start Battle' button that features two crossed swords at the top. The button should be rectangular with a rugged, stone-like frame made of pixelated textures, fitting the mystical island theme. In the center of the button, include bold. Above to add the text, add two pixelated swords crossed diagonally, with sharp, silver blades and decorated hilts. The swords should have a slight shine or glint effect to make them stand out. The background of the button should have a gradient from dark blue to black, giving it a dramatic and intense atmosphere. Small pixelated particles or sparks should subtly emanate from the swords, creating a sense of anticipation for the battle. The overall look should be epic and inviting, encouraging players to press the button to begin the combat."
