Edited: OP is long gone.
Bold statement: If you have a question about the rules or cards of the new set, and if the answer is on the forum, then its in this post. Search by the keyword like the spell name or effect. Feel free to add questions as we go too.
1) Fireweaving: EDIT july16th overrulled previous answer.
The lady Warlock cannot move burn markers onto Flame Immunity or burn-proof creatures. You choose which order [mwcard=MWSTX2FFQ01] Adramelech's Torment[/mwcard] and Fireweaving take place.
If you are immune to something you cannot have that condition on you. So If you are flame immune, you cannot have burn tokens on you. It doesn't matter how they were moved their.
2) Flame +1 applies to every attack, including doublestrike and [mwcard=MW1I02] Battle Fury[/mwcard] attacks, unlike Melee +1. It also increases your effect die roll by one. Flame -4 and tough -4 together can reduce a fire attacks effect die from 1 to -7, but attacks always roll at least one attack die.
3 & 9) Demonic Reward & [mwcard=MWSTX2FFQ02] Bloodfire Helmet[/mwcard]: If your demon has multiple attacks with one action(eg. [mwcard=MW1I02] Battle Fury[/mwcard]), and it applies a burn marker before the last attack against an object, the later attack against that creature gains the bonus.
4) [mwcard=MW1I07] Dissolve[/mwcard] and [mwcard=MW1E29] Nullify[/mwcard]: If a dissolve is nullified, you have to pay the 2 mana from [mwcard=MWSTX2FFQ05] Harshforge Plate[/mwcard], but not the 2 mana from the object having a rune nor the 4 mana from [mwcard=MWSTX1CKE01] Armor Ward[/mwcard]
5) Runes & Power Rune: Each rune specific requirements to be placed on an equipment, so read those before trying to put armour +1 on a ring of command or something. Power Rune cannot be placed on equipment which alters the cost of spells(Discount rings, [mwcard=FWQ06] Horn of Gothos[/mwcard]). The equipment must have a spell action on it. The Power Rune still gives a discount when you use a spell action to change the bound spell to spellbind equipment.
6) Battle Orders and [mwcard=MWSTX2FFC07] Gurmash[/mwcard]: Your warlord and Gurmash may both cast one Battle Order in the same round. You may stack the same order twice on the same creature, just like a [mwcard=FWI06] Power Strike[/mwcard]. Ex. [mwcard=FWC06] Goblin Slinger[/mwcard] can receive "Take Aim" twice to gain piercing+4 for his ranged attack.
7) [mwcard=MWSTX2FFI02] Conquer[/mwcard] and Walls: You cannot target walls with the spell "Conquer". You can cast a Wall with your free action from the "Conquer" spell.
7.1) By conquering and recasting an epic conjuration of which you already have a copy in your spellbook, you may end up having two copies of that Epic conjuration in play, but not two copies of a unique or legendary conjuration. Ex. two [mwcard=FWJ03] Barracks[/mwcard] spells controlled by one mage is ok, but not two [mwcard=MWSTX2FFJ04] Armories[/mwcard].
8) [mwcard=FWC04] Goblin Builder[/mwcard] and [mwcard=MWSTX2FFC09] Otto Kronig[/mwcard]: The goblin builder cannot repair walls. Otto has the same language, but includes a bracketed section stating he can target walls. There is plenty of goblin builder walls discussion elsewhere.
10) [mwcard=MWSTX2FFC10] Sardonyx[/mwcard]: You do not take two damage. You lose two MAX LIFE. Same situation as when you make a Bloodreaper. I only say this here because so many people get it wrong (including myself once upon a time).
11) [mwcard=MWSTX2FFE01] Adramelech's Touch[/mwcard]: You do not have the opportunity to reveal this enchantment between the moments when your opponent rolls his burn dice and removes burn conditions that rolled a zero.
12) [mwcard=MWSTX2FFE06] Lion Savagery[/mwcard] and Charge: You gain the Charge bonus if you move out of a zone, move into that zone, and attack over one creature's turn. Good examples are [mwcard=MW1C37] Thunderift Falcon[/mwcard], [mwcard=MW1C07] Cervere[/mwcard], and an elusive lady beastmaster. Charge bonus does not apply to teleport movement([mwcard=MW1C05] Blue Gremlin[/mwcard]).
13) [mwcard=MWSTX2FFE02] Akiro's Favor[/mwcard]: You can reveal this after the roll you'd like to reroll. It cannot be used to reroll an enemy defense. With this card and [mwcard=MW1J09] Temple of the Dawnbreaker[/mwcard], players choose in order of initative whether to reroll.
14) [mwcard=MWSTX2FFI03] Disarm[/mwcard] & Disable: Disable on equipment removes every single thing which effects your mage(attack bars, armor, flame -2, unmoveable, ect) but maintains things that effect the spell itself(unique, cantrip, ect).
15) [mwcard=MWSTX2FFC11] Sersiryx, Imp Familiar[/mwcard] can cast [mwcard=MWSTX2FFA01] Devil's Trident[/mwcard]
16) [mwcard=MWSTX2FFQ04] General's Signet Ring[/mwcard]: If you deploy a discount ring on yourself, during that same deployment, you can immediately use the ring to discount something else being deployed. You can still discount a [mwcard=FWJ03] Barracks[/mwcard]creature if your mage didn't have to contribute mana.
17) [mwcard=MWSTX2FFQ05] Harshforge Plate[/mwcard]: you pay the extra 2 mana when you cast the enchantment and not when you reveal it. also see "4)".
18) Unstoppable and [mwcard=MW1J22] Tanglevine[/mwcard], [mwcard=DNJ10] Stranglevine[/mwcard], [mwcard=FWJ07] Quicksand[/mwcard]: EDIT :march2015: These cannot target an uncontainable creature.
19) [mwcard=MWSTX2FFC13] Wildfire Imp[/mwcard]: Unlike other teleporting creatures, the teleport requires line of sight to the zone(but not line of sight to the burn marker) and has no range limitation. Burn markers on walls can't be used for this teleport.
20) [mwcard=MWSTX2FFQ01] Adramelech's Torment[/mwcard]: [mwcard=FWQ09] Sectarus[/mwcard] counts as an attached curse, so you can give yourself a burn marker.
21) [mwcard=MWSTX2FFI06] Defend[/mwcard]: does not count as a guard action, so [mwcard=MWSTX1CKC06] Guardian Angel[/mwcard] does not get healed
22) [mwcard=MWSTX2FFI01]Combustion[/mwcard]: Cannot be intercepted.
----------------
I'm adding a oldschool Warlock and Warlord section for the old cards which are getting misused now that ppl are trying warlock and warlord again. I'll just add them when I see them in reviews and talks n such, so dont expect much breadth here.
a) The curse sword can't kill something AND add a curse to it(ie rise again)
b) You can stack copies of the same incantation on a creature such as power strike
c) Walls: cannot be affected by anything which only targets a zone, including imp teleport, goblin builder repair, conquer, zone attacks, ect.
