Raid: Shadow Legends is a free to play fantasy battle game. You have heroes to collect which you can enhance in several ways:

• Level up to max for their Rank, then Upgrade to next Rank and level up again up to 6* Level 60.
• Nine item slots with a variety of semi-random equipment you can find (not Diablo-level random but you can scum looking for items with specific extra bonuses).
• Each item belongs to a set and if you equip the set (2 or 4 items, depending on set) the hero gets an additional bonus.
• Each item can be enchanted with glyphs which increase the bonuses a bit but every bit counts.
• Each item can be upgrade from level 0 to 12.
• Three skill trees (which I think are the same for each hero) and you can only choose two trees to upgrade and only about half the skills can be activated.
• Ascend once per Rank level which gives a bit of attribute boost and for some heroes enables an extra skill.

For adventuring there are many things do:

• Campaign with a dozen locations, each location with 7 encounters. Each encounter you can get one to three stars, three stars if you beat it with two heroes (out of four possible slots) and no deaths. The campaign has four difficulty levels.
• Dungeons are locations for special items. Potion keeps used for Ascension. Minotaur for scrolls used up upgrade skills. Spider, Ice Golem, Dragon and Fire Knight for rarer equipment than those found in Campaign.
• Arena for semi PvP play. As you beat players you get points and rank up in the arena. At the end of the week you get random rare items based on your arena rank.
• Faction Wars. Each hero belongs to one of a dozen or so factions. In the Wars you use heroes of the same faction to beat enemies and collect glyphs.
• Clan Boss. A huge monster that you and the rest of your clan can fight. Get rare item chests (different sets than available anywhere else, and Arena has different item sets than found anywhere else) and if the boss is defeated then double prizes.

The actual battles are not that complicated. Each encounter is three rounds of 4x4 fights (Campaigns only, everywhere else you can use five heroes). When a hero goes you choose one of your skills (base attacks kill and up to three other skills) then tap on target. And that's all the choice in a battle -- there is no movement or delaying to sequence attacks. It's still a lot tactical finesse because of which heroes you use. But after a few battles it gets both long and boring so I use auto battle almost all the time.

There's a bunch of other little things. And of course silver and gems which you can purchase with real money. Actually the in-apps are very expensive compared to other games. I bought two ($5 for 500 gems, $10 for 2100 gems over the course of a month) and I hope that'll be it for me (there is a gem mine which I upgraded and with daily bonus that's 25 gems per day, not a huge amount but most f2p games don't give you this ability).

I've been playing almost two months. It's very grindy but entertaining without being extremely complicated. It has replaced Star Trek Timelines as my f2p game.

Negatives:

• It's resource intensive and drains battery quickly.
• If I go away or 15 minutes then on reload it has to restart the game which takes 15 to 30 seconds.
• Every time you go to home screen, which you do often, you get one to three ads for in-app special purchases.
