Otherland Weapons: Which to Upgrade

It has been one of the toughest things to traverse Otherlands (Very Hard) even after the release of Japanese ver. 2.0. The weapons to be made and upgraded with items gathered there also have kept their top-notch status. Below is a list of the weapons and their bonuses when upgraded at the maximum level. It shows my recommendation at the column "Rate." I still use Rate S weapons almost every occasions and Rate A very frequently.

Name	Type	Region	P.ATK	M.ATK	Bonus I	Bonus II	Rate
Delos Xiphos		Buroki	185	22	ELEM RSS +20%	MP cost -20%	B
Crescent Shadow		Buroki	192	32	DMG up when HP is low	SPD +30	S
Hecate's Shadow		Buroki	199	8	PHS RSS +20%	MP restoration up	B
Red Spider Lily		Ratle	166	47	Poison added	Condition DMG up	B
Bulk Faust		Ratle	181	30	Non-ELEM DMG up	MP restoration up	S
Ulcanactos		Ratle	185	22	ELEM DMG up	MP cost -20%	S
Prometerium		Ratle	166	121	Non-ELEM DMG up	DMG up when HP is low	B
Grati Aegis		Elzion	22	185	Stat effect RSS +20%	PHS RSS +20%	A
Aceto Vita		Elzion	22	185	SPD +30	HP restoration up	S
Oracle's Fury		Elzion	107	180	Stat effect RSS up 20%	PHS RSS +20%	B

ELEM: Elemental, DMG: Damage, PHS: Physical, RSS: Resistance.

Weapons with SPD bonus especially Aceto Vita are must-have for me to effectively conquer quests and stages available even after the release of ver. 2.0 and later. Grati Aegis is useful when you confront enemies of strong physical attack.

Ulcanactos was probably what most JP players concentrated on upgrading and equipped AS Suzette with until introducing a new weapon, Tears of Fallen Dark Princess (lovely name?! Chunibyo...) dedicated to normal Suzette at ver. 2.0.70. However, Ulcanactos is still the best Lance for attackers such as Cetie and Hismena. While the amount of the Elemental damage bonus is not revealed, based on my measurement it is +20%. Suppose the damage is 10,000 without any upgrade, it will be 12,000 upon upgrading it to level 10.

Amy, upon class change to 5 star, acquires a triple hit non-elemental attack skill, and many equip her with Bulk Faust. The damage bonus seems to be +50%, which means to me that Non-Elemental attack can substantively deliver the same range of damages as Elemental.
