Creates a crystal of ice around the player, which absorbs any incoming damage (while the crystal is intact, player is invincible). Maintaining a crystal consumes a certain amount of MP at regular intervals. Crystal disappears when it's own HP is depleted, or if the player runs out of MP. Unlike it's Fire counterpart, absorbs Physical damage more efficiently.
i'm planning to level cold to 60, for phy defence purposes only for my int based char. after seeing those movies and reading the description, when using this cold buff at level 60 (Extreme Wall lvl2) the player will have a hp increase of 5368(?) and will be also able to widthstand phy based attacks better because of this 54 phy absorption? so when doing jobwars or plain pvp, an int char will have an extra stack of hp (+5k!) when using this buff or am i seeing this all wrong? the mp required to maintain the buff at level is 269mp every 5 seconds?
i know that it does take a while to buff up this skill, but taking a few hits from a pure glaiver during buffing can be compensated with 100% autopot
just wondering if this buff is worth the pharming, so if anyone has hands on experience please let me know
