We are going to start RTL and I want to make sure that we understand some rules correct.

1. Is heroes always level 1 in RTL, OL gets 4 tokens and 2 cards per tirn (unless some effects in play)?

2. When equipment that allow you to carry more items are destroyed (pack of holdings) , all extra items are lost immediatelly?

3. At the final battle some maps allow heroes to come back to town while OL's avatar is in game. Heroes can stay in city as long as they want and heal themselves while OL get no advantage for that time. ( looks like no chance for OL heroes have too much mobility while OL have no cards). Shouldn't those maps remove glyphs after OL avatar comes to game?

4. There are some ranged itemswith sourcery from WoD addon (Surcerous Orb with Sorcery 3) . Sorcery looks more like magic ability and item looks like magic item, but it is ranged. Something wrong here?

5. Using necromancy skill possible to get monster on your side. Can this animated monster move to the next level anyhow?

Here are some answers hopefully:

1. Is heroes always level 1 in RTL, OL gets 4 tokens and 2 cards per tirn (unless some effects in play)?

-there are no levels for the heroes per se, as the campaign progresses they purchase health and/or fatigue upgrades, more power dice, and more skills (effectively 'leveling them up' but that terminology or process does not apply), the OL normally draws 1 threat per hero (so yes 4 unless something modifies it) and 2 cards per turn.

2. When equipment that allow you to carry more items are destroyed (pack of holdings) , all extra items are lost immediatelly?

-not sure of the ruling on this, my thought it this. The pack of holding is an other (?), it can be carried in a backpack and therefore cannot be destroyed by crushing blow (which can only destroy an equipped item), if it is actually equipped then I would say all items in it are destroyed from a simple logical standpoint but as for a ruling not sure if there has been one. (NOTE: did not have pack of holding in front of me, the mechanics may be different from what I put here).

3. At the final battle some maps allow heroes to come back to town while OL's avatar is in game. Heroes can stay in city as long as they want and heal themselves while OL get no advantage for that time. ( looks like no chance for OL heroes have too much mobility while OL have no cards). Shouldn't those maps remove glyphs after OL avatar comes to game?

-once avatar appears as gylphs are removed from the board and no one can go to town (it is in RtL base rule book).

4. There are some ranged itemswith sourcery from WoD addon (Surcerous Orb with Sorcery 3) . Sorcery looks more like magic ability and item looks like magic item, but it is ranged. Something wrong here?

-may appear odd buts works nonetheless, sorcery allows one point of range or damage for each point of sorcery.

5. Using necromancy skill possible to get monster on your side. Can this animated monster move to the next level anyhow?

-interesting question, since familiars travel with you I would be inclined to say 'necromanced' monsters can as well, but again not sure if there has been a ruling on it.
