Players with level 90 Smithing may claim a one-off free seed from Lady Ithell if they have not completed the Xena-phile Elite task of the Tirannwn Tasks. If players already have an attuned crystal seed or weapon or have recently dropped an item, they cannot claim the seed.
While the requirements for claiming the seed from Lady Ithell cannot be boosted in any way, players are able to use temporary boosts in order to create the weaponry.
A degraded weapon can be taken to Eluned, or Islwyn (after The Light Within), to be recharged, unless it has fully degraded and reverted back to a seed. In that case it must be created again using harmonic dust. Eluned may say "I can only do partial recharges after fully attuning one seed for you", thus disallowing the recharge option. In that case, having her create a standard Crystal bow with a crystal weapon seed, the player degrading it, and then returning to her for a recharge clears this issue. Simply take a crystal weapon seed and talk to her. After some dialogue, you will be able to ask her to sing you something for a fee (1,000,000) - ask her to sing you a crystal bow. After this is done, you will be able to recharge all attuned crystal weapons without a problem.
