Shard is one of the requirements to forge a special sword. A player can earn SHARDS by forging normal weapons (1 weapon = 1 shard) or by staking SKILL.
If there are multiple events active at the same time, a player can pick the specific special event to earn shards for when minting normal weapons. Shards rewards from staking can be claimed into any active event shard.
In the shards tab, a player can view shards balances for all events and can convert it to different event shards. The conversion rate is 1:3 and rounds up only if a player is converting all of the remaining shards from an event. A player can also monitor and claim shards staking rewards in this tab.
