Gentlemens, Tactician mode is way too fucking hard.
Any special talents I should get for my team? I'm a Cleric, a Rogue and two wizards.
What level are you? Tactician can be pretty brutal starting out but it gets much easier once you get to act 2 and start getting some gear. Through thievery and lucky charm you can buy almost all the most expensive/effective gear you like and then pickpocket the money back. You can steal once per character, so leveling thievery on multiple characters is recommended. (Thievery starts shining once you can steal 10k gold per character, which I think is 5 points)
If you're having a hard time not getting spotted while trying to steal (i.e. crowded area), place the rest of your party talking to whatever other characters are around, and spin the NPC's 180 degrees away from your current thief. After stealing start moving cause they'll be coming for you. Barter ain't that useful, stack up Lucky Charm on one character instead.
Summoning is very powerful, especially so if you, with the help of gear, rush it up to 10 points. That way you get a beefy ass summon (summon incarnate, also heard good things about the necro summon) which you can infuse into whatever element you like, then add melee/ranged/rogue skills with the extra infusions.
Rangers are also very powerful, esp. with crossbows. Try to always end the turn on your squishies with something that cloaks you / gives you evasion or teleports you (cloak/evade/nether swap or try to break LoS) if you can't CC or nuke an enemy target down that turn. Try to teleport multiple enemies on top of each other and then spam AoE + grenades if they will contribute to a spell combination, like poison and fire or water and lightning.
"The pawn" is a great talent on any character imo. Makes moving cost 1 less ap, so you can move short distances for 0 ap.
I'd respec the rogue into a ranger and give him/her far out man. Use elemental arrows when you need magic damage. Most targets either have more magic armor or more phys armor, which you should try to take advantage of. If your ranger is an elf, spam flesh sacrifice and then later the skill book with gives you more damage the more distance you have + the skill which lets you fly up in the air to get a single shot with the +height damage modifier. On top of that, use flight when you can to get an actual height advantage from Huntsman. (I bought a pink crossbow on my ranger in act 2 at lvl 10 which gives me +20% crit, making my total crit end up at around 45% (give or take, can't check right now) with "Hothead", flame rune in necklace and some other +%crit on items.)
Consider using all types of crowd control you can! Polymorph gives you chicken touch at lvl 1 and wings for your cleric/fighter, your mages and your ranger. Contemplate getting haste/fortify/magic armour on as many characters as you can. "+armor/mag armor-over-time" spells can also be helpful.
Abuse LoS every fight and find good positioning before fights & of course during fights (hide behind walls, kite enemies into chokepoints etc) Use "The Pawn" and the flight skill to get an ap advantage over the enemies. You can make the enemy melee attackers waste a lot of ap by using your escape/skills and flight.
Give all your mages shields, go 12 con and 1 pt in warfare for shield throw. (It's good to have both phys and magical damage on every character). This will buff your survivability on your mages considerably. (You can also give your casters 12 strenght to equip some beefier armor, or 12 finesse and a nice bow/x-bow but the latter is a high-risk-high-reward play. Dual wands can also be good for damage and something like burning+poison, but again, lessens your survivability )
Give all your character some sort of heal/status-ailment cure, preferably multiple ones.
I like to have chameleon cloak on all my characters as well, plus aero 2 on most for teleport/evade, nether swap etc. If you end your turn with cloak you can kinda use it as a taunt of sorts and force the enemy to attack your tankiest character. Huntsman 2 for tactical retreat and first aid ain't bad either for a low cost.
Most skill trees have worthwhile skills around 1-2 points worth picking up on multiple characters. Warfare has some nice knockbacks and a teleport aswell.
I'm was very tired while typing this so it might have been a little messy and poorly structured. Moreover, I noticed I probably used the word "abuse" way too many times in this post (English isn't my first language, but that isn't a good excuse). Nevertheless, I hope at least some of the above advice helps. As soon as you get some gear, a good bow for the ranger and reach 10 in summoning the game becomes much more manageable.
Good luck!
Get a summoner and, from what I read, a ranger instead of a rogue.
Essentially the TL
R of my long ass post above. I agree!
I swear every merchant in this game is a psychic. They even know when I lot closed crates and chest and they are not in the room.
Heh, I feel ya! But are you checking their line of sight by holding shift? If you are in the dark red, they can spot you. If you are in the "lighter shade of red", they can't spot you if you sneak (someone correct me if I'm wrong, but this is how I've come to interpret it) You can avoid getting caught in a crowded area by separating your characters and positioning 3 of your teammates talking to NPC's 180 degrees away from your thief while your thief sneaks around and steals/pickpockets.
