Who needs CHTPs when you can get this?

20 to all stats, 10% HP and MP, 15 HP and MP, 3 attack and magic attack, 100 defense and magic defense, and has 5 slots. It can be traded once by use of the Platinum Scissors of Karma.

With the Dragon Stone, HT neck does more all stats, does the hp/mp% more defense.
The 6 slots on accessory scrolls for a 10% scroll will get you 3 stats a scroll, or 18 total (single) stats for all the slots, CHT gets 15 all +stats from Dragon Stone, leaving 2 extra slots to do with as you please. Like 6 more power stat. (21 single stat, 15 all others)
Not to mention the Chaos Scrolled HT necks running around with 300-450 extra def/mDef.

The set bonus comes at the cost of wearing fairly plain set pieces, a bad ring and an o.k. belt your total bonuses could be better with other specific loot that is not part of the set netting you less over all productivity for going with the set itself.

Sadly you can't just use 3 dragon stones on CHT neck and get +45 all stats, it flags it after the first one so you cant use another.
