Soul of the Scythe: Thanks for taking time to try to help! That said...
1. I repeat, "GuildWiki should add this limitation to their
upgrade article," which is where most people would look first for quick reference. I'm glad relevant information exists elsewhere in GuildWiki, but it's often of little help if that information is omitted from the main articles.
2. I repeat, "...since some kinds of collector wands are unavailable in Nightfall (e.g. a Holy Rod with HCT of Divine Favor spells)." I've looked over GuildWiki's database on Elona collector items, and according to them no wand exists with that spec. My lead Elona character is at The Desolation; my impression is that no staff or wand thusfar has the HCT mod, but I could be mistaken.
3. My error about insignias and inscriptions being Factions...I meant Nightfall. Mind and spirit willing, but fingers weren't, and all that. But the main point I'm making about consistent use of types of mechanisms in the game is still valid IMO. Exceptions unnecessarily complicate things.
4. Tohsedi's wand does
NOT offer "Halves casting time of Divine Favor spells (Chance: 20%)" which is what I want. My Holy Rod from the Crystal Desert is apparently singular in providing this mod, so far as I can see. That makes the inability to apply a Wand Wrapping to it disappointing.
5. I'm not looking for sympathy, only help.
FWIW:
In Kourna, collectors usually give wands with HSR and a damage bonus, foci with RPD -x and a Health bonus.
In Vabbi, collectors usually give wands with HSR and an Energy bonus, foci with HSR and a Health bonus.
In The Desolation, collectors usually give wands with HSR and a damage bonus, foci with RPD -5 (20%) and a Health bonus.
In The Realm of Torment, collectors usually give wands with HSR and a damage bonus, foci with RPD -2 (Enchanted) and a Health bonus (Enchanted); the end game collectors likewise don't offer wands or staves with HCT.
So if HCT is the mod you want, you'd have to look outside of Elona (wands
and staves). Cantha does have staves which can receive a Adept staff head for some HCT, but I never got far enough in Cantha to reach the requisite collectors. Rylan Paval in the Crystal Desert has one, but getting Spiney Seeds is a major problem.
Comment:
No one is perfect, not me, not GuildWiki. While we all have a vested interest in helping GuildWiki get better, only the truly generous take time to help me, so I appreciate what help I got here.
