Multiclass proficiencies

Glorious Raphael,
The answer is in Player’s Handbook p. 164 before Multiclassing Proficiencies Table: “When you gain a level in a class other than your first, you gain only some of that class’s starting proficiencies…” , so you are procient in all your first class skills, after that follow the Multiclassing Proficiencies Table.

Have a epic adventure.

Behind the Screens 1: DM’s Cheat Sheet – Update

Master Rodney tell us how to improve DM adventure, especially storytelling with interludes, random encounters and recap.
Interludes are short texts that can describe your world, your story arc or character aspects.
The recap is like the one at the beginning of TV shows: it helps to focus on the following events.

A must read.

Gorgeous UPDATE!:

Light and Vision

Mighty Raphael,
these rules are a a little bit scattered in the Player’s Handbook.
You can find a generic description at p.183 without distances.
After, rules are based on the power of light source: if you check Equipment section p.151-153 you’ll find that Candle, Lantern and Torch have different Vision radius (Bright and Dim).
The generic Visibility Outdoors rules are in Dungeon Master’s Guide p. 243

Otherwise more spcific rules for Vision in Outdoor are lost in a old tome called Advanced Dungeons&Dragons Wilderness survival guide, but distances rules differs from PHB 5e, so be careful.

Dim Light (Twilight and Dawn) the range of normal vision is 300 yards. This means that a humanoid with an unobstructed view can see a size M creature to recognize its basic form. A creature or object of size S is visible from 150 yards away, and one of size L is visible from a distance of at least 600 yards.
Darkness (Moonlight) the range is 50 yards, 25 for Small Creature/Object, 100 for Large

Enjoy your quest!
