WC Combo Buffs

Can someone please explain the combo buffs at lvl 70, 72, and 74. I just lvl to 70 and I am not sure how to get my combo buff. It is not listed in the L2 skills. Which amulets do I need? Do I take the amulet to the Orc guild and get the new skill there? Please be as specific as you can. Your help is greatly appreciated!

Find the book/amulet/whatever for the skill.

Double click on it.

The combo buffs amulets are drop only, so you need to hunt for them or buy from other players.

Then you need to double click or right klick on the amulet to learn the skill.

i had 2 weeks problems with learning them, when just i asked in ally chat "hi, how and when do i learn the combo buffs" the answer was "just click them twice"

then the magic happen

for the amulets, just find someone to party with him, i got 1 amu at 68 in IoP (with 78 Adventuter )

Amulets for WC drops:
under Giants Cave
in Witch
in Dark Omen

Chant of Combat (70) - Witches Catacomb (Crypt Guard)
Chant of Critical Attack (72) - Silent Valley (Soldier of Ancient Times)
Chant of Blood Awakening (74) - Dark Omen Catacomb (Crypt Preacher)

Aw, thanks for the info. I could not find this anywhere! Happy hunting.
