In the game Runescape the level black dragon is 144. The black dragons are powerful monsters, an anti-dragon shield, a dragonfire shield, or an antifire potion or even both of them is highly recommended when fighting them.
if you want a black square shield, kill moss giants until they drop one. if you want a black kiteshield, you have to buy it from the grand exchange. i dont think its that expensive (unless its trimmed).
