I am returning to the game after a 20 year break and am quickly trying to catch up on everything. I am doing lots of converting of old models to round bases right now, or putting models on bases for the first time ever (yay 3rd edition models). I am seeing lists that say 1 drop or 4 drop. What does this mean? For the summon spells, do you have to deploy this troop for the mage to know this spell? Or, do the mages know the spell because it is in the army manual? Can you summon out of dead troops or should I have extra units at the ready to summon? When I start a game, Can I look at my opponent's roster? Any advice on quickly learning what I should care killing first or avoiding? I'm excited to get back on the field, but am feeling a bit overwhelmed by all the information I need to know to get playing again. Thanks!
