I found a lot of excellent resources on this donjon site. These are rules that I find very useful for Converting D&D3.5 Monsters to 5e This is a good 5th edition SRD (System Reference Document). Redkat’s 5E D&D Tools also has a great set of random generators. It has traps, treasure, lots of different items, magic and downtime events. This is a Dungeons & Dragons 5th Edition Encounter Calculator. These include a Character Builder, Race Builder, Background Builder, Spells, Monsters, Items, Combat Tracker, Encounter Builder, Monster Builder, Spell Builder, Feat Builder, Class Builder and more. Here you will find an excellent set of tools. Perhaps you will find some of these useful as well.
Here are some useful web sites that I have ran across over the last couple of years.
