Endurance; Perception (1d20+7=10, 1d20+5=11)
Being drained by the ritual and fighting the owlbears exhausted the warlock and running in circles doesn't help. He blindly stumbles through the underbrush until the group stops and discusses the direction again.
He takes the amulet out, draws a diagram of the stars again and puts the amulet in an empty place within.
Those listening very closely and being close to the warlock may here some mumbling.
"I know you don't like this, but I will use you if I have to. Nothing here will break me, like THEY didn't."
He takes off the gloves again and displays that purple tattoo you saw during the ritual, but this time no blood is involved. Instead he bends his considerable will to break the amulets shield.
Arcana to 'break' into the amulet (1d20+13=20)
Shaking his head after a minute, he turns to the gnome and deva discussing the past.
"I have a feeling this amulet could be a lot more useful if I could break it's shields. I didn't have time to attune correctly after we appeared here and the thing is stronger here. Would you are to help? You too, Vermitrax.
Let's see now..." he gathers small circle...
"Don't worry, it will not hurt like the last time, this isn't full blown ritual...just keep the magic alive and channel into me. Except or you, Vermitrax, you keep everything together."
He starts the ritual, words of power in fey language of the eladrin easily coming. He channels the magic, shapes it into the spear, blocking off outside access to the weave so the amulet has no other source of magic but itself and Martelai...the shields he leaves in capable hands of his comrades. Just before he thrusts the spear at the amulet he changes his approach. He sings to the thing. He sings at the best of his ability, trained at bardic college, possessed of the knowledge of magic of eladrin from mage college, legends of his people. He sings of the glory of the Feywild, of the power of its lords, of the beauty of endless forests and magical glades, the joy of its people. This time, he leaves the stars out of it, letting the amulet rest on a living leaf, focusing on his hated heritage, remembering his childhood, the songs and games he got beaten at, the riddles and knowledge he excelled at and finally all the little things that make one an eladrin. Grace. Intelligence. Magic. Eternal and exquisite life of Feywild flowing around him.
Arcana (1d20+13=25) - hopefully with some aid-anothers from others ( should be auto-successes )
