For typical training, focus on wisdom and attack rating
(+6 wisdom, +5 attack rating, +1 coordination, -1 intelligence)
coral icon: +5 wisdom -2 intelligence
moonstone charm: +1 wisdom +1 intelligence +1 coordination
bark bloodtoken: +5 attack rating
It is helpful to wear a destiny or scholar's item if you use many items enchanted like this, to prevent low intelligence
Instead of using a bark bloodtoken, you might use that slot to increase a stat for better roundtime
For those who do not like the negative intelligence, use a deadwood idol (+2 wisdom +1 stamina) instead of the coral icon
