As dylan said you can get sharpness on kits.
And those kits come with donor ranks like gold,lapis ,emerald,diamond and higher.
Kits have enchanted diamond armor and enchanted sword(coal kit has unenchanted armor and sword)
To get those kits you either need to buy em from others who have donor rank or those who bought those items from people with donor ranks.
You can also buy the ranks by yourself and get all the perks that come with em.
Closing as its resolved.
