Lizard is the race with the worst synergy with the Rogue archtype. It starts with +1 Persuasion, and Rogues would rather spend points onto Thievery and sometimes Sneak, the other racial bonus is a couple of resistances, and the racial skill creates a fire surface which Rogues HATE because they have to move around to hit enemies in the back.
You can if you really want to, it's just Lizard is the worst choice.
Ignore the Guerrilla Talent, it is virtually useless because Sneaking in combat costs 4 AP and therefore is totally useless. The Pawn is good.
There are actually a few different ways to make a Rogue or Shadowblade.
1.
Maximum Damage RogueThis Rogue basically tries to maximize damage from both regular backstabs AND skills. It puts most of its points into Warfare and Scoundrel. Warfare affects ALL Physical damage, Scoundrel only increases the critical damage (backstabs).
- It takes all the Rogue damage skills like Throwing and Sawtooth Knife.
- It may take the Executioner Talent instead of the Pawn, but that's at your discretion.
- Dual-wields daggers for increased damage.
- Elf is good for this Rogue thanks to Flesh Sacrifice.
2.
High Evasion RogueThis Rogue focuses more on survival.
- It puts points into Dual Wielding and Scoundrel. Dual Wielding increases Dodge.
- It probably takes skills like Chameleon Cloak (Polymorph) and Uncanny Dodge (Aerothurge), as well as escape skills.
- It takes the Parry Master Talent for increased Dodge, and probably Duck Duck Goose as well.
- Dwarf is good for this Rogue thanks to its racial bonuses to health and dodge.
3.
Position Master RogueThis Rogue focuses on manipulating the mobility of itself and others.
- It takes a lot of mobility skills, like Favourable Wind, Teleport, and Netherswap from Aerothurge, as well as Cloak and Dagger and Tactial Retreat from Huntsman.
4.
Debuff Master ShadowbladeThis Rogue focuses on inflicting status effects to enemies. It uses mobility skills to get around the battlefield and inflicting statuses to assist teammates into finishing enemies off.
- It takes Chloroform and Chicken Claw.
I would have written more detail but I'm tired.
