Rules on receiving Clan War rewards:
1. The player's clan must be among the top high scorers (usually in the top 3).
2. Only those who scored points in Clan Wars can receive event rewards.
3. There are some tasks where several players can score points in Clan Wars (only a few best scores are taken into account).
4. A player is removed from the task ranking when other players score more points. When that happens, the player's task score is set to zero.
