These are the images I used to create the custom dice for my Gladiator game. Dice are seperated into three types: Attack, Defence and Bonus.
Attack dice are rolled on your turn and have 3 sword icons, 2 foot icons and 1 starburst icon.
Defence dice are rolled when blocking an attack and have 3 shield icons, 2 foot icons and 1 starburst icon.
Bonus dice can be rolled any time and have 3 sword/shield icons, 2 foot icons and 1 starburst icon.
