Good hybrid species:
Tengus, merfolk, nagas, draconians, Deep dwarf
Good hybrid gods:
Ashenzari, cheibriados, nemelex
Note: all 3 of these gods can be tough to get used to, especially cheibriados. I personally recommend ashenzari, he us the easiest to understand.
Personal favorite hybrid combos:
MfGl of oku--> Chei
NaFi of Chei
DrFE of ashenzari
OgHu of ashenzari
DDNe of ashenzari/Kiku/nemelex
DDEE of Makhleb
TeFE of ashenzari/nemelex
MfTm of Chei
MfIE of ashenzari/Chei/vehumet
TeAE of ashenzari
Generic advice:
Starting out playing a solid melee character and switching to support magic later on is often the easiest choice.
Necromancy(especially the spells in the necronomicon) are often the key to success with hybrids.
Your first objective is surviving lair and orcish mines. Your second objective is finding haste(if you are a Chei follower, controlled blink)
Weapon training:
Generally speaking, the best weapons to use are either polarms or maces. Polarms are good because they have reaching and tend to scale well with the games difficulty, and they combo well with Chei followers and Mf's. Maces are good because whips of elec are incredibly powerful during early-midgame, can be used to give you extra AC(protection brand) if needed, provide versatility in choices later on(shields vs 2hander) and are easily the most common kinds of weapons in the game. Also, they both cross train with staves, which you should start probably start training the moment you find a lajatang of speed, or even elec(even if you plan on using a shield, staff skill for magic staves can be good for late game). As far as training goes, you will probably want to dump in a bunch at first and then start trickling until you hit in-delay.
Note: I'm not exactly a very good player, I tend to go for whatever is fun rather than whatever is optimal. The advice here is likely not going to lead you to your next amazing victory, but i hope it will lead you in the right direction.
To all new players: Ignore all strategy guides posted on the wiki, ask questions in the Advice forum, players with lots of posts normally have the best advice.
