110 skills (for greater rune) vs. old - enchanted skill? Eviscerator + others

[Sw0rd 0]

Anyone can tell me what about enchanted "old" skills, when I learn new 110 skill for greater rune?

What about old skill enchant? For example +10 - 5.6% p.def on Eviscerator - new - almighty gravity skill will work alone, and I'll lost that 5.6% p.def?

almighty gravity gives p.atk +40%,p.atk critical damage +10%,p.def +10%,m.def +10%,and confusion/danger zone resistance +30. Cannot use old and new together. 30 minute buff with 30 sec cool down. Cannot enchant.
