You get a surprise round on the crocodiles, which are about 40 ft. from the bank of the river, which is around 10 ft. from you. 

Gordon, going first, will throw two battered swords at the giant crocodile. If one hits, he activates his fire giant rune.

Gordon's swords both missed. 

On his turn, Zavier will cast hex on the giant crocodile, then launch two eldritch blasts.

On his turn, Jetsam will shoot a crossbow bolt at the nearest croc. Attack: 11 Damage: 7

Nice! Ruaccek's barrage of attacks takes down the huge crocodile. 

Gordon, going next, will target the injured crocodile with some improvised weapon attacks. 

Attack: 12 Damage: 6

He takes it down, leaving two crocodiles remaining. Zavier switches the hex to the nearer crocodile as a bonus action, then launches a set of scorching rays. 

Attack: 18 Damage: 7 (plus 5 if first crocodile remains alive)

Attack: 14 Damage: 2 (plus 4 if first crocodile remains alive)

Attack: 20 Damage: 7 (plus 3 if first crocodile remains alive)

Attack: 24 Damage: 9 (plus 1 if first crocodile remains alive)

Zavier was close, but off by one point of damage, he had to direct the first three rays at one crocodile, resulting in less damage to the third crocodile than he'd like.

Same. Jetsam fires another crossbow bolt. Attack: 25 Damage: 12

Ruaccek and Jetsam's crossbow bolts fell the last crocodile. Zavier moves forward, and, with Gordon's (and anyone else who decides to) help, he drags the crocodile corpses to the other bank. He begins pouring necromantic energy into one of them, casting [spell]animate dead]/spell] on its bones. (I've be granted permission to use larger corpses as materials for more than one skeleton)

We get downtime of: 4 (The next threat may interrupt Zavier's spellcasting)

In those 15 minutes, Zavier animates a total of 9 skeletons, cobbled together with bones to large to animate in their proper organisation. He equips them with crossbows, rapiers, shields, and scale mail armor, and gives them standing orders to travel with him, arrayed at least 5 ft. from any creature unless conditions prevent it, and attack any creature that harms or threatens them, Zavier, or the party. 

Unless anyone else has actions to do in those 15 minutes, I'll roll the next threat.
