Both wizards use magic, while the Saradomin wizard can use poisonous melee.

Coordinate clues will always summon a Zamorak wizard (inside the wilderness) or a Saradomin wizard (outside the wilderness) excluding one in the duel arena. Hard clue scrolls are usually longer and harder, often involving clues with medium/high level quests to access the area the clue sends you. If you die in lower Wilderness to a monster you will always keep the clue whether protected or not. In lower Wilderness however (level 20 or lower), in PvP death, an unprotected clue scroll will stay on the ground for up to 1 hour.

It should be noted, that if a player dies in the Wilderness with a clue scroll in level 20 or higher Wilderness, it WILL DISAPPEAR regardless of whether it's a PvP death or not, unless it is an item kept on death or if the player has a clue box otherwise, the clue scroll will disappear entirely. If you have dropped the prior clue scroll while having done some of the steps on that, the next clue scroll you get will have retained the prior one's steps. Players can use the right-click 'check' option on a Clue scroll to check the number of steps they have completed on the Treasure Trail. After the update of 18 June 2015 it is now possible to have one Clue scroll of each tier at a time, while previously you could not get any clue scroll at all if you already had one, until you completed it or dropped it. There are six different levels of Clue scrolls, the higher level ones having a wider variety of rewards. Clue scrolls are the starting point of Treasure Trails - rewarding treasure hunts throughout Old School RuneScape. A clue scroll is a reward that can be obtained randomly from killing monsters, playing minigames, looting implings, fishing, woodcutting, or mining.
