Note, I played Dark Age of Camelot for 12 years, didn't game for 1 year and only started Lineage Jan 2021.
I'm a Yul Sagittarius and I have done similar things to my main as you suggest with minor differences.
I have a +15 Bloody bow R99 with plans to make it a 110 when money permits.
The two skills I use most , heavy arrow rain and pinpoint are both enchanted to +20, I have raised my main attack and main defense forgotten skills to +10 (the forgotten skill books are a pain to acquire). I have +3 dyes, level 2 artifact book, 5 good agathion and 5 good jewels. +10 exalted armour was the logical choice.
